On arm64 we use the iommu base address as an xref. This fails when
the address has the lower 32-bits in common with another iommu as
they will share an xref.

Parse named nodes from IORT ACPI on arm64

Add the ability to map named components from IORT to their
SMMU or ITS node in order to setup interrupts.
It is now possible to find a node by its name (substring) and
resource ID similar to PCI nodes.
This is needed by work on a driver for NXP's Second Generation
Data Path Acceleration Architecture (DPAA2).

When mapping MSI/MSI-X interrupts throught he Arm IORT ACPI tables we may

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.

arm64 acpi: Add support for IORT table

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).
