[PATCH v2 2/3] arm64: dts: renesas: rzg2ul-smarc: Enable Audio

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Enable Audio on RZ/G2LC SMARC EVK by adding ssi1 pincontrol entries
to the soc-pinctrl dtsi and ssi1 and cpu sound_dai nodes to the board
dtsi.

Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
Reviewed-by: Geert Uytterhoeven <geert+renesas@xxxxxxxxx>
---
v1->v2:
 * started using cpu_dai node instead of snd_rzg2l in board dtsi.
 * Added rb tag from Geert.
