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.

Add a driver to provide access to imx6 on-chip one-time-programmble data.
Make it possible to access the ocotp registers before the ocotp device is attached, by establishing a temporary mapping of the registers when necessary.
It turns out Freescale cleverly made the ocotp device compatible across several different families of SoCs, so move it to the freescale directory and prefix everything with fsl rather than imx6.
Convert the imx6 sdhci "R1B fix" from a busy-loop in the interrupt handler to a callout.
Increase the wait time for acquiring the SD bus from 10 to 250ms.
If no compatible cards were found after probing the SD bus, say so.
Add timeout logic to sdhci, separate from the timeouts done by the hardware.
After a timeout, reset the controller using SDHCI_RESET_CMD|SDHCI_RESET_DATA rather than SDHCI_RESET_ALL; the latter turns off clocks and power, removing any possibility of recovering from the error.
Add a helper routine to depth-search the device tree for a node with a matching 'compatible' property.

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.

Convert lpc from using fdt_immr style to arm_devmap_add_entry() to make static device mappings.
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.
Add #include <machine/fdt.h> to a few files that used to get it via pollution
Enable the mv cesa security/crypto device by providing the required property in the dts source, and adding the right devices to the kernel config.
Remove dev/fdt/fdt_pci.c, which was code specific to Marvell ARM SoCs, related to setting up static device mappings. Since it was only used by arm/mv/mv_pci.c, it's now just static functions within that file, plus one public function that gets called only from arm/mv/mv_machdep.c.
Switch RPi to using arm_devmap_add_entry() to set up static device mapping.
Allow 'no static device mappings' to potentially work.
Don't try to find a static mapping before calling pmap_mapdev(), that logic is now part of pmap_mapdev() and doesn't need to be duplicated here.

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.
