This commit provides attachment of xhci-platform for A38X boards, making
it possible to mount FreeBSD world from USB3.0 flash. 'xhci' device was
added to files.mv (as optional) and kernconf of Armada38x was enhanced.
It was also necessary to open programmable memory windows of USB3.0.
fdt_win_setup needed improvement so it's able to traverse through
children of internal-regs node.

After ARM_INTRNG introduction, MPIC code needed several modifications:
- IRQ resource and its handler added
- several DEVMETHODs of INTRNG interface implemented
- defines enhanced to ensure code compiles as well for AXP as for A38X
- added dummy MSI_IRQ, ERR_IRQ defines for Armada38x
- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in
kernconf file and regs of MPIC corrected in dts file.
Instead of modifying Armada38X DTS, offsets to CPU registers defined in
driver were changed. That required restoring 'reg' property of mpic node
in ArmadaXP to state compliant with Linux DTS.
Additionally, required ARM_INTRNG definitions were added to mv_common.c.

on ARM with LPAE we could see an address space of up to 40 bits. On ARM
u_long is only 32 bits so the memory size will be truncated, possibly to

Summary:
As part of the migration of rman_res_t to be typed to uintmax_t, memory ranges
must be clamped appropriately for the bus, to prevent completely bogus addresses
from being used.

Newer Allwinner MMC implementations use a different FIFO register offset
(0x200 instead of 0x100). Since the FDT uses the same compat string for

the interrupt framework is also going to be used by another (MIPS)
architecture. IPI implementations may vary much across different
architectures.
An IPI implementation should still define INTR_IPI_COUNT and use
intr_ipi_setup_counters() to setup IPI counters which are inside of
intrcnt[] and intrnames[] arrays. Those are used for sysctl and ddb.
Then, intr_ipi_increment_count() should be used to increment obtained

Linux-driven changes to the way the chip's two interrupt controllers are
defined (we only support one of them) led to no interrupt processing, so
the system would hang after device instantiation. This workaround just
rewrites the FDT data on the fly to get interrupt handling back under the
control of the main GIC device.
If/when we ever support deep sleep modes that involve powering down the
main GIC, we'll have to undo this change, write a driver for the GPC-PIC,
and somehow manage the handoff of responsibilities between the two drivers
as the chip transitions in/out of deep sleep mode.
Only L2 PIPT cache is supported for __ARM_ARCH >= 6.
In fact, this is just a pure proclamation as this option is used
only in armv4 specific files now.

There are quite internal definitions in pte-v4.h and pte-v6.h headers
specific for corresponding pmap implementation. These headers should be
included only in very few files and an intention is to not hide for
which implementation such files are.
Further, sys/arm/arm/elf_trampoline.c is an example of file which
uses armv4 like pmap implementation for both armv4 and armv6 platforms.
This is another reason why pte.h which includes specific header
according to __ARM_ARCH is not created.
