ASoC: cs42l42: Ensure 0dB full scale volume is used for headsets
[ Upstream commit aa18457c4af7a9dad1f2b150b11beae1d8ab57aa ]
Ensure the default 0dB playback path is always used.
The code that set FULL_SCALE_VOL based on LOAD_DET_RCSTAT was
spurious, and resulted in a -6dB attenuation being accidentally
inserted into the playback path.
