Convert Renesas Interrupt Controller bindings documentation to json-schema.
Signed-off-by: Yoshihiro Kaneko <ykaneko0929@xxxxxxxxx>
---
v3
- Add interrups to required.
- Update the example to according to the current implementation.
v2
- Add SPDX tag.
- Document interrupt-contoller, reg, interrupts, power-domains and resets
properties.
- Add addtionalProperties.

-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)

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