acpi: Add functions to declare ARM GIC V3 hardware
For GICD and GICR a SOC needs to implement 2 callbacks to get the base
of those interrupt controllers.
For all the cpu GIC the code loops over all the DEVICE_PATH_GICC_V3
devices in a similar fashion to how x86 lapics are added. It's up to the
SOC to add those devices to the tree.
