Revert r330897:
This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code.
Revert with prejudice.
This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes.
Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes.

MFC r304459,r305527:
r304459: INTRNG: Rework handling with resources. Partially revert r301453. - Read interrupt properties at bus enumeration time and store it into global mapping table. - At bus_activate_resource() time, given mapping entry is resolved and connected to real interrupt source. A copy of mapping entry is attached to given resource. - At bus_setup_intr() time, mapping entry stored in resource is used for delivery of requested interrupt configuration. - For MSI/MSIX interrupts, mapping entry is created within pci_alloc_msi()/pci_alloc_msix() call. - For legacy PCI interrupts, mapping entry must be created within pcib_route_interrupt() by pcib driver itself. r305527: Fix MIPS INTRNG (both FDT and non-FDT) behaviour broken by r304459

Use uintmax_t (typedef'd to rman_res_t type) for rman ranges.
On some architectures, u_long isn't large enough for resource definitions. Particularly, powerpc and arm allow 36-bit (or larger) physical addresses, but type `long' is only 32-bit. This extends rman's resources to uintmax_t. With this change, any resource can feasibly be placed anywhere in physical memory (within the constraints of the driver).
Why uintmax_t and not something machine dependent, or uint64_t? Though it's possible for uintmax_t to grow, it's highly unlikely it will become 128-bit on 32-bit architectures. 64-bit architectures should have plenty of RAM to absorb the increase on resource sizes if and when this occurs, and the number of resources on memory-constrained systems should be sufficiently small as to not pose a drastic overhead. That being said, uintmax_t was chosen for source clarity. If it's specified as uint64_t, all printf()-like calls would either need casts to uintmax_t, or be littered with PRI*64 macros. Casts to uintmax_t aren't horrible, but it would also bake into the API for resource_list_print_type() either a hidden assumption that entries get cast to uintmax_t for printing, or these calls would need the PRI*64 macros. Since source code is meant to be read more often than written, I chose the clearest path of simply using uintmax_t.
Tested on a PowerPC p5020-based board, which places all device resources in 0xfxxxxxxxx, and has 8GB RAM. Regression tested on qemu-system-i386 Regression tested on qemu-system-mips (malta profile)
Tested PAE and devinfo on virtualbox (live CD)

Introduce a RMAN_IS_DEFAULT_RANGE() macro, and use it.
This simplifies checking for default resource range for bus_alloc_resource(), and improves readability.
This is part of, and related to, the migration of rman_res_t from u_long to uintmax_t.

Convert rman to use rman_res_t instead of u_long
Summary: Migrate to using the semi-opaque type rman_res_t to specify rman resources. For now, this is still compatible with u_long.
This is step one in migrating rman to use uintmax_t for resources instead of u_long.
Going forward, this could feasibly be used to specify architecture-specific definitions of resource ranges, rather than baking a specific integer type into the API.
This change has been broken out to facilitate MFC'ing drivers back to 10 without breaking ABI.

SIMPLEBUS: Don't panic if child device doesn't have devinfo set. Strictly speaking, missing devinfo is error which can be caused by instantiating child using device_add_child() instead of BUS_ADD_CHILD(). However, we can tolerate it.

Make simplebus a base class of ofwbus. This allows the elimination of duplicated code in the two classes, and also allows devices in FDT-based systems to declare simplebus as their parent and still work correctly when the FDT data describes the device at the root of the tree rather than as a child of a simplebus (which is common for interrupt, clock, and power controllers).

Introduce ofw_bus_reg_to_rl() to replace part of common bus code
Instead of reusing the same reg parsing code, create one, common function that puts reg contents to the resource list. Address cells and size cells are passed rather than acquired here so that any bus can have different default values.

Fail to probe on simplebus nodes that lack a "ranges" property.
Increasingly, FDT data has the "simple-bus" compatible string on nodes that have children, but we wouldn't consider them to be busses. If the node lacks a ranges property then we will fail to attach successfully, so fail to probe as well.

Replace multiple nearly-identical copies of code to walk through an FDT node's interrupts=<...> property creating resource list entries with a single common implementation. This change makes ofw_bus_intr_to_rl() the one true copy of that code and removes the copies of it from other places.
This also adds handling of the interrupts-extended property, which allows specifying multiple interrupts for a node where each interrupt can have a separate interrupt-parent. The bindings for this state that the property cells contain an xref phandle to the interrupt parent followed by whatever interrupt info that parent normally expects. This leads to having a variable number of icells per interrupt in the property. For example you could have <&intc1 1 &intc2 26 9 0 &intc3 9 4>.

Follow r261352 by updating all drivers which are children of simplebus to check the status property in their probe routines.
Simplebus used to only instantiate its children whose status="okay" but that was improper behavior, fixed in r261352. Now that it doesn't check anymore and probes all its children; the children all have to do the check because really only the children know how to properly interpret their status property strings.
Right now all existing drivers only understand "okay" versus something- that's-not-okay, so they all use the new ofw_bus_status_okay() helper.

Retire machine/fdt.h as a header used by MI code, as its function is now obsolete. This involves the following pieces: - Remove it entirely on PowerPC, where it is not used by MD code either - Remove all references to machine/fdt.h in non-architecture-specific code (aside from uart_cpu_fdt.c, shared by ARM and MIPS, and so is somewhat non-arch-specific). - Fix code relying on header pollution from machine/fdt.h includes - Legacy fdtbus.c (still used on x86 FDT systems) now passes resource requests to its parent (nexus). This allows x86 FDT devices to allocate both memory and IO requests and removes the last notionally MI use of fdtbus_bs_tag. - On those architectures that retain a machine/fdt.h, unused bits like FDT_MAP_IRQ and FDT_INTR_MAX have been removed.

Teach nexus(4) about Open Firmware (e.g. FDT) on ARM and MIPS, retiring fdtbus in most cases. This brings ARM and MIPS more in line with existing Open Firmware platforms like sparc64 and powerpc, as well as preventing double-enumeration of the OF tree on embedded PowerPC (first through nexus, then through fdtbus).
This change is also designed to simplify resource management on FDT platforms by letting there exist a platform-defined root bus resource_activate() call instead of replying on fdtbus to do the right thing through fdt_bs_tag. The OFW_BUS_MAP_INTR() and OFW_BUS_CONFIG_INTR() kobj methods are also available to implement for similar purposes.
