ASoC: wcd9335: Add support to enable vbat feature 



Add support to enable vbat monitor feature on tasha codec.
Vbat module monitors the battery voltage and updates the
gain on rx path if battery voltage falls below certain
threshold value. This module can prevent brown-out
scenarios on the mobile devices when the loads are heavy
on the battery and it can also prolong battery life.
