RZ/V2H, RZ/V2N, and RZ/G3E support external audio clock inputs
(AUDIO_CLKA, AUDIO_CLKB, AUDIO_CLKC) that can be used by the Audio Clock
Generator (ADG) to derive internal audio clocks. These clocks are optional
and their frequencies are set by the board.

Update the bindings to allow these optional clocks for all RZ/V2H family
SoCs.

My bot found errors running 'make dt_binding_check' on your patch:

See https://patchwork.kernel.org/project/devicetree/patch/20260319155334.51278-2-john.madieu.xa@bp.renesas.com

The base for the series is generally the latest rc1. A different dependency
should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above
error(s), then make sure 'yamllint' is installed and dt-schema is up to
date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note
that DT_SCHEMA_FILES can be set to your schema file to speed up checking
your schema. However, it must be unset to test all examples with your schema.
