Introduce ofw_bus_reg_to_rl() to replace part of common bus code
Fix endianness on FDT read in ARM GIC

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.

Rename OF_xref_phandle() to OF_node_from_xref() and add a new function that provides the inverse translation, OF_xref_from_node().

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.

The kernel stack guard pages are only below the stack pointer, not above.
Remove unnecessary double-setting of the thread's onfault state in copyinstr().
Open Firmware mandates that certain cross-references, in particular those in /chosen, be ihandles. The ePAPR spec makes those cross-reference phandles, since FDT has no concept of ihandles. Have the OF FDT CI module interpret queries about ihandles as cross-reference phandles.
Real OF systems have an ihandle under /chosen/stdout, not a phandle. Use the right type.
Rearchitect platform memory map parsing to make it less Open Firmware-centric.
Remove fdtbus_bs_tag definition, which is now obsolete. The remainder of this file is also slated for future demolition.
Return the correct IEEE 1275 code for "nextprop".
Use the common Open Firmware PCI interrupt routing code instead of the duplicate version in dev/fdt.
Configure interrupt sense based on device tree information.
Simplify the ofw_bus_lookup_imap() API slightly: make it allocate maskbuf internally instead of requiring the caller to allocate it.

Add a new function (OF_getencprop()) that undoes the transformation applied by encode-int. Specifically, it takes a set of 32-bit cell values and changes them to host byte order. Most non-string instances of OF_getprop() should be using this function, which is a no-op on big-endian platforms.
Use the new function all over the place.

Add a helper routine to search for a compat string in a table that associates compat strings with arbitrary values that mean something to the driver. This is handy for drivers that support several variations of similar hardware and need to know which one matched.
