ASoC: codecs: rv1106_codec: add support properties to configure init gains

Browse Source 
Add support init gains:

MIC  Gain     ALC Gain (0dB: 0x06)   Lineout Gain (0dB: 0x1a)
0dB  (0x01)    min: -9.0dB (0x00)     min: -39.0dB (0x00)
20dB (0x02)    max: +37.5dB (0x1f)    max: +6.0dB (0x1f)
12dB (0x03)   step: +1.5dB           step: +1.5dB
