Use newly added R-Car GPIO Gen3 fallback compat string
in place of now deprecated non-generation specific
R-Car GPIO fallback compat string in the DT of the r8a7796 SoC.

This should have no run-time effect as the driver matches against
the per-SoC compat string before considering the fallback compat string.

"audio_clkout" is dummy clock of <&rcar_sound 0> to avoid clock loop
which invites probe conflict. Thus <&rcar_sound 0> and "audio_clkout"
should be same value.

On commit 2752660a ("arm64: dts: renesas: ulcb: sound
