* CRISv32 Interrupt Controller

Interrupt controller for the CRISv32 SoCs.

Main node required properties:

- compatible : should be:
	"axis,crisv32-intc"
- interrupt-controller : Identifies the node as an interrupt controller
- #interrupt-cells : Specifies the number of cells needed to encode an
  interrupt source. The type shall be a <u32> and the value shall be 1.
- reg: physical base address and size of the intc registers map.

Example:

	intc: interrupt-controller {
		compatible = "axis,crisv32-intc";
		reg = <0xb001c000 0x1000>;
		interrupt-controller;
		#interrupt-cells = <1>;
	};
