arm64: dts: renesas: Factor out Gray Hawk Single board support 



Move the common parts for the Renesas Gray Hawk Single board to
gray-hawk-single.dtsi, to enable future reuse.

 * [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%
