[PATCH v3 6/9] dt-bindings: interrupt-controller: realtek,rtl-intc: Add rtl9300-intc

[Chris Packham <chris.packham@alliedtelesis.co.nz>]

Add a compatible string for the interrupt controller found on the
rtl930x SoCs. The interrupt controller has registers for VPE1 so these
are added as a second reg cell.

Notes:
    Changes in v3:
    - Use items to describe the regs property
    Changes in v2:
    - Set reg:maxItems to 2 to allow for VPE1 registers on the rtl9300. Add
      a condition to enforce the old limit on other SoCs.
    - Connor and Krzysztof offered acks on v1 but I think the changes here
      are big enough to void those.
