ASoC: wcd9335: add TXFE power mode mixer control 



WCD9335 has different power mode for analog mic inputs
The design is that two consecutive microphones share
same power mode. Along with power mode on analog mic
register, corresponding mode would have to be set on
decimator when it is connected to analog microphone.
