MFC r272109, r272181:
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.

Add the imx sdhci controller.
Move Open Firmware device root on PowerPC, ARM, and MIPS systems to a sub-node of nexus (ofwbus) rather than direct attach under nexus. This fixes FDT on x86 and will make coexistence with ACPI on ARM systems easier. SPARC is unchanged.
Add the missing ')' at end of sentence. Reword it to use a more common idiom.
Pass the kernel physical address to initarm through the boot param struct.
Make functions only used in vfp.c static, and remove vfp_enable.
Fix __syscall on armeb EABI. As it returns a 64-bit value it needs to place 32-bit data in r1, not r0. 64-bit data is already packed correctly.
Use abp_physaddr for the physical address over KERNPHYSADDR. This helps us remove the need to load the kernel at a fixed address.
Remove references to PHYSADDR where it's used only in debugging output.
Dynamically generate the page table. This will allow us to detect the physical address we are loaded at to change the mapping.

Open Firmware interrupt specifiers can consist of arbitrary-length byte strings and include arbitrary information (IRQ line/domain/sense). When the ofw_bus_map_intr() API was introduced, it assumed that, as on most systems, these were either 1 cell, containing an interrupt line, or 2, containing a line number plus a sense code. It turns out a non-negligible number of ARM systems use 3 (or even 4!) cells for interrupts, so make this more general.
Provide a simpler and more standards-compliant simplebus implementation to get the Routerboard 800 up and running with the vendor device tree. This does not implement some BERI-specific features (which hopefully won't be necessary soon), so move the old code to mips/beri, with a higher attach priority when built, until MIPS interrupt domain support is rearranged.
Allow nesting of simplebuses.
Add a set of helpers (ofw_bus_get_status() and ofw_bus_status_okay()) to process "status" properties of OF nodes.
Fix one remnant endian flaw in nexus.

Add two new interfaces to ofw_bus: - ofw_bus_map_intr() Maps an (iparent, IRQ) tuple to a system-global interrupt number in some platform dependent way. This is meant to be implemented as a replacement for [FDT_]MAP_IRQ() that is an MI interface that knows about the bus hierarchy. - ofw_bus_config_intr() Configures an interrupt (previously mapped) based on firmware sense flags. This replaces manual interpretation of the sense field in bus drivers and will, in a follow-up, allow that interpretation to be redirected to the PIC drivers where it belongs. This will eventually replace the tables in /sys/dev/fdt/fdt_ARCH.c
The PowerPC/AIM code has been converted to use these globally, with an implementation in terms of MAP_IRQ() and powerpc_config_intr(), assuming OpenPIC, at the bus root in nexus(4). The ofw_bus_config_intr() will shortly be integrated into pic_if.m and bounced through nexus into the PIC tree.
Factor out MI portions of the PowerPC nexus device into /sys/dev/ofw. The sparc64 driver will be modified to use this shortly.
Allow PIC drivers to translate firmware sense codes for themselves. This is designed to replace the tables in dev/fdt/fdt_ARCH.c, but will not happen quite yet.
Do not map IRQs twice. This fixes PowerPC/FDT systems with multiple PICs, which would try to treat the previously-mapped interrupts from fdt_decode_intr() as interrupt line numbers on the same parent PIC.
Remove some of the code required for supporting ssm(4) on SPARC in favor of a more PowerPC/FDT-focused design. Whenever SPARC64 is integrated into this rework, this should be (trivially) revisited.

Add driver for the PAPR VSCSI virtual SCSI controller. This lets FreeBSD install directly into standard POWER LPARs, as found for example in QEMU. The core of this device is the SCSI RDMA protocol as also found in Infiniband. The SRP portions of the driver will be factored out and placed /sys/cam in the future to allow them to be used for IB storage. Thanks to Scott Long for a great deal of implementation help.

Merge in support for PAPR-compliant (Power Architecture Platform Requirements) systems from the projects/pseries branch. This in principle includes all IBM POWER hardware released in the last 15 years with the exception of POWER3-based systems when run in 64-bit mode. The main development target, however, has been the PAPR logical partition support that is the default target in KVM on POWER and QEMU -- mileage may vary on actual hardware at present. Much of the heavy lifting here was done by Andreas Tobler.
