arm: lib: Add GICV2 driver
Add a generic GICV2 driver that:
- parses the DT and generates the ACPI MADT subtables
- implement of_xlate() and allows irq_get_by_index() to return the
correct interrupt mappings
Map DT interrupts to ARM GIC interrupts as follows:
- Interrupt numbers ID32-ID1019 are used for SPIs
- ID0-ID15 are used for SGIs
- ID16-ID31 are used for PPIs
TEST: Booted on QEMU raspb4 using GICV2 driver model generated MADT.
