ARM: at91/aic: add irq domain and device tree support
Add an irqdomain for the AIC interrupt controller. The device tree support is mapping the registers and is using the irq_domain_add_legacy() to manage hwirq translation. The documentation is describing the meaning of the two cells required for using this "interrupt-controller" in a device tree node.
