ASoC: dt-bindings: renesas: Fix R-Car Gen4 SoC-specific compatibles

Browse source 
make dtbs_check:

    arch/arm64/boot/dts/renesas/r8a779g0-white-hawk.dtb: sound@ec5a0000: compatible: 'oneOf' conditional failed, one must be fixed:
	    ['renesas,rcar_sound-r8a779g0', 'renesas,rcar_sound-gen4'] is too short
	    ...
	    'renesas,rcar_sound-r8a779h0' was expected

The list of SoC-specific compatible values for R-Car Gen4 SoCs is
mutually-exclusive, just like for other R-Car SoC generations, so it
should use an enum.
