MLK-17979: ASoC: rpmsg_wm8960: add mixer control for ADC input
The microphone only connect to left input, when record stereo channel data, the right channel is mute. Add 'ADC Data Output Select' mixer control that user can select the wanted configure. The default setting is 'Left Data = Left ADC; Right Data = Left ADC'. Signed-off-by: Shengjiu Wang <shengjiu.wang@nxp.com>
