Introduce ACPI_IRQ_MODEL_GIC which is needed for ARM64 as GIC is used, and then register device's gsi with the core IRQ subsystem. acpi_register_gsi() is similar to DT based irq_of_parse_and_map(), since gsi is unique in the system, so use hwirq number directly for the mapping. We are going to implement stacked domains when GICv2m, GICv3, ITS support are added.
