Set the acpi_ops structure as static const where applicable. The
The structure is not accessible from outside of drivers and is not
going to be modified at runtime. The structure may be unused in a
couple of drivers depending on their configuration, mark those
sites with __maybe_unused .

arm: lib: Add GICV2 driver2024-10-27T23:24:13ZPatrick Rudolphpatrick.rudolph@9elements.com2024-10-23T13:20:04Zurn:sha1:df8d759d9db17b55d6283a9a1d84d196e9cc1dd4
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.
