arm64: dts: renesas: gray-hawk-single: Add Sound support

Browse Source 
Because R-Car V4M supports only 1 SSI, it cannot use Playback/Capture at
the same time.  Hence select Playback as default.

/*
* [How to use Sound]
*
* Because R-Car V4M has only 1 SSI, it cannot handle both Playback/Capture
* at the same time. You need to switch the direction which is controlled
* by the GP0_01 pin via amixer.
*
* Playback (CN9500)
* > amixer set "MUX" "Playback" // for GP0_01
* > amixer set "DAC 1" 85%
* > aplay xxx.wav
*
* Capture (CN9501)
* > amixer set "MUX" "Capture" // for GP0_01
* > amixer set "Mic 1" 80%
* > amixer set "ADC 1" on
* > amixer set 'ADC 1' 80%
* > arecord xxx hoge.wav
