When mapping MSI/MSI-X interrupts throught he Arm IORT ACPI tables we may
need to ignore an interrupt controller even if it is within the bounds the
entry describes. When the SMMUv3 is not using GSIV (non-MSI/MSI-X)
interrupts we need to read the defined field. The Performance Monitoring
Counter Group always ignores the first table entry.

Print warnings for some bad kernel configurations (like NUMA disabled
with multiple domains). Check and report some firmware errors (like
incorrect proximity domain entries).

Add new file arm64/acpica/acpi_iort.c to support the "IO Remapping
Table" (IORT). The table is specified in ARM document "ARM DEN 0049D"
titled "IO Remapping Table Platform Design Document". The IORT table
has information on the associations between PCI root complexes, SMMU
blocks and GIC ITS blocks in the system.
The changes are to parse and save the information in the IORT table.
The API to use this information is added to sys/dev/acpica/acpivar.h.
The acpi_iort.c also has code to check the GIC ITS nodes seen in the
IORT table with corresponding entries in MADT table (for validity)
and with entries in SRAT table (for proximity information).

ACPI driver requires special functions to be provided by machdep code.
Add temporary stubs to satisfy the compiler when both "pci" and "acpi"
are enabled in the kernel configuration file.

drivers, one for fdt, one for acpi. It then uses this to decide if it will
use fdt or acpi.
The GICv2 (interrupt controller) and Generic Timer drivers have been
updated to handle both cases.
As this is early code we still need FDT to find the kernel console, and
some parts are still missing, including PCI support.
