ASoC: sdm845: add independent clock support on codec

WCD934X codec has single master clock supply widget for both
playback and recording paths. Adding separate clock supply
for playback and recording paths will help handle low power
audio recording usecases without affecting playback usecases.
Change is to enable separate clock supply widgets for playback
and recording paths.
