ASoC: wcd9xxx: Enhance class H controller to support dynamic CP voltage
Codecs can operate at a lower voltage for vdd_buck, whereas
this voltage source being shared, it is not guaranteed that the
codec will always receive exactly the requested voltage. Add support
to class H controller to handle dynamic switching of the chargepump
voltage.
