[PATCH v2 01/24] dt-bindings: clock: renesas: Add audio clock inputs for RZ/V2H family

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.
