Subject: [PATCH v2] dt-bindings: spi: renesas,sh-msiof: Fix 'unevaluatedProperties' warnings

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

arch/arm64/boot/dts/renesas/r8a77951-ulcb-kf.dtb: spi@...90000: Unevaluated properties are not allowed ('power-domains', 'resets' were unexpected)
	From schema: Documentation/devicetree/bindings/spi/renesas,sh-msiof.yaml

The main problem is that SoC DTSI's include power-domains and resets
property, whereas the renesas,sh-msiof.yaml has 'unevaluatedProperties:
false'. So just add optional power-domains and resets properties.
