DT bindings for the R-Mobile/R-Car/RZ/G interrupt controller

Required properties:

- compatible: must be "renesas,irqc-<soctype>" or "renesas,intc-ex-<soctype>",

	      and "renesas,irqc" as fallback.

  Examples with soctypes are:

    - "renesas,irqc-r8a73a4" (R-Mobile APE6)

    - "renesas,irqc-r8a7743" (RZ/G1M)

    - "renesas,irqc-r8a7744" (RZ/G1N)

    - "renesas,irqc-r8a7745" (RZ/G1E)

    - "renesas,irqc-r8a77470" (RZ/G1C)

    - "renesas,irqc-r8a7790" (R-Car H2)

    - "renesas,irqc-r8a7791" (R-Car M2-W)

    - "renesas,irqc-r8a7792" (R-Car V2H)

    - "renesas,irqc-r8a7793" (R-Car M2-N)

    - "renesas,irqc-r8a7794" (R-Car E2)

    - "renesas,intc-ex-r8a774a1" (RZ/G2M)

    - "renesas,intc-ex-r8a774c0" (RZ/G2E)

    - "renesas,intc-ex-r8a7795" (R-Car H3)

    - "renesas,intc-ex-r8a7796" (R-Car M3-W)

    - "renesas,intc-ex-r8a77965" (R-Car M3-N)

    - "renesas,intc-ex-r8a77970" (R-Car V3M)

    - "renesas,intc-ex-r8a77980" (R-Car V3H)

    - "renesas,intc-ex-r8a77990" (R-Car E3)

    - "renesas,intc-ex-r8a77995" (R-Car D3)

- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in

  interrupts.txt in this directory

- clocks: Must contain a reference to the functional clock.

Optional properties:

- any properties, listed in interrupts.txt, and any standard resource allocation

  properties

Example:

	irqc0: interrupt-controller@e61c0000 {

		compatible = "renesas,irqc-r8a7790", "renesas,irqc";

		#interrupt-cells = <2>;

		interrupt-controller;

		reg = <0 0xe61c0000 0 0x200>;

		interrupts = <0 0 IRQ_TYPE_LEVEL_HIGH>,

			     <0 1 IRQ_TYPE_LEVEL_HIGH>,

			     <0 2 IRQ_TYPE_LEVEL_HIGH>,

			     <0 3 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&mstp4_clks R8A7790_CLK_IRQC>;
