arm64: dts: renesas: r9a09g047e57-smarc: Add DA7212 audio codec support

Browse Source 
RZ/G3E SMARC board has a DA7212 audio codec connected via I2C1 for
sound input/output using SSI3/SSI4 where:
 - The codec receives its master clock from the Versa3 clock
   generator present on the SoM,
 - SSI4 shares clock pins with SSI3 to provide a separate data
   line for full-duplex audio capture.

Enable audio support on RZ/G3E SMARC2 EVK boards with a DA7212 audio
codec.
