[PATCH] dt-bindings: display: bridge: renesas, dw-hdmi: Fix 'unevaluatedProperties' warnings

[Lad Prabhakar]

With 'unevaluatedProperties' support implemented, there's a number of
warnings when running dtbs_check:

arch/arm64/boot/dts/renesas/r8a774b1-hihope-rzg2n-rev2-ex-idk-1110wr.dtb: hdmi at fead0000: Unevaluated properties are not allowed ('resets' was unexpected)
	From schema: Documentation/devicetree/bindings/display/bridge/renesas,dw-hdmi.yaml

The main problem is that SoC DTSI's are including resets property, whereas
the renesas,dw-hdmi.yaml has 'unevaluatedProperties: false'. So just add
optional resets property to the binding.
