The compander system is intended to increase the dynamic
range of an input signal. But for the wcd9310 codec,
this feature is to use companding in a novel way in the DAC
converter path to increase the signal noise ratio.
The change is to add the compander support to wcd9310
codec. The dynamic compander enable/disable during stream
playback is not supported.
