audio: Enabling STEREO channel capture
audio: Enabling STEREO channel capture

The legacy code inherited from asus/grouper device was forcing the
channel configuration to be MONO if channel mask was not configured
for MONO. Removed the code so that actual channel mask is configured
and hence support STEREO capture.
