ASoC: wcd9xxx: Use common functionality to change micbias voltage
Currently helicon codec driver hardcodes the micbias voltage to 1.8
volts and hence does not support micbias voltage other than 1.8 volts.
Add support for the helicon codec driver to use the existing common
drivers to be able to support micbias voltages other than 1.8 volts.
