ARM: gic: add irq_domain support
Convert the gic interrupt controller to use irq domains in preparation for device-tree binding and MULTI_IRQ. This allows for translation between GIC interrupt IDs and Linux irq numbers. The meaning of irq_offset has changed. It now is just the number of skipped GIC interrupt IDs for the controller. It will be 16 for primary GIC and 32 for secondary GICs.
