[PATCH 1/5] arm64: renesas: r8a7796: Add external audio clocks

[Kuninori Morimoto]

Hi Geert

> Add the external audio clocks as zero Hz fixed-frequency clocks.
> Boards that provide these clocks should override them.
> 
> Based on commit 623197b90c7aa97c ("arm64: renesas: r8a7795: Sound SSI
> PIO support").
> 
> Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
