ASoC: codecs: msm8916-wcd-analog: get micbias voltage from dt
This patch adds bindings in DT to provide required micbias voltage which
could be specific to board. With this new binding, now the mic bias
voltage is left at hardware default value if the device tree does not
specify any mic bias voltage value. Correct micbias value is required
for mbhc buttons to work.
