Subject: [PATCH v2 5/8] dt-bindings: interrupt-controller: realtek,rtl-intc: Add rtl9300-intc

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.

Signed-off-by: Chris Packham <chris.packham@...iedtelesis.co.nz>

Notes:
    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.
