[PATCH] ARM: dts: r8a7742-iwg21d-q7-dbcm-ca: Add missing camera regulators

[Geert Uytterhoeven <geert+renesas@xxxxxxxxx>]

make dtbs_check:

    arch/arm/boot/dts/r8a7742-iwg21d-q7-dbcm-ca.dt.yaml: ov5640@3c: 'AVDD-supply' is a required property
	    From schema: Documentation/devicetree/bindings/media/i2c/ovti,ov5640.yaml
    arch/arm/boot/dts/r8a7742-iwg21d-q7-dbcm-ca.dt.yaml: ov5640@3c: 'DVDD-supply' is a required property
	    From schema: Documentation/devicetree/bindings/media/i2c/ovti,ov5640.yaml
    arch/arm/boot/dts/r8a7742-iwg21d-q7-dbcm-ca.dt.yaml: ov5640@3c: 'DOVDD-supply' is a required property
	    From schema: Documentation/devicetree/bindings/media/i2c/ovti,ov5640.yaml

Fix this by describing the missing regulators.
