This brings in the "-w" option from bhyve to ignore unknown MSRs.
It will make debugging Linux guests a bit easier.

Add a helper routine to depth-search the device tree for a node with a
matching 'compatible' property. This probably has a short half-life (as
do most of the fdt_ functions), but it helps solve some near-term needs
until we work out the larger problems of device instantiation order
versus the order of things in the fdt data.

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.

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.

Reimplement fdt_intr_to_rl() in terms of OFW_BUS_MAP_INTR() and
OFW_BUS_CONFIG_INTR(). This function is only used by simplebus, so will
likely be moved there in the future.

Remove dead code. Most of this was in an #if 0 block; the rest is not
used and duplicates functionality in dev/ofw.

MFP4: 223121 (FDT infrastructure portion)

Implement support for interrupt-parent nodes in simplebus. The current
implementation requires that device declarations have an interrupt-parent
node and that it point to a device that has registered itself as a
interrupt controller in fdt_ic_list_head and implements the fdt_ic
interface.

Bump per-device interrupt limit to more reasonable default.

Some hardware like DMA and GPIO controllers might require
more then 8 interrupts per device instance.
