This patch sets the default internal micbias voltage to 1.8v. This
default value is required for mbhc buttons to work. Also adds dt
bindings to allow the board level file to specify the required default
micbias value.
What was the default previously?
This was set to 2.7v previously for special headsets which have high
impedance.
