Subject: [PATCH v3 4/5] ARM: dts: r7s72100: Add IRQC device node

Enable support for the IRQC on RZ/A1H, which is a small front-end to the
GIC.  This allows to use up to 8 external interrupts with configurable
sense select.

v3:
  - Use interrupt-map (+ #address-cells and interrupt-map-mask) instead
    of renesas,gic-spi-base,

v2:
  - Add Reviewed-by,
  - Add "renesas,gic-spi-base".
