ASoC: intel/sdw_utils: Add volume limits to CS35L56
Merge series from Stefan Binding <sbinding@opensource.cirrus.com>: Both CS35L56 and CS42L43 have maximum volumes above 0dB. However, for many use cases, this can cause distorted audio, depending various factors, such as other signal-processing elements in the chain, for example if the audio passes through a gain control before reaching the amp or the signal path has been tuned for a particular maximum gain in the amp. In the cases where systems use the soc_sdw_* drivers, audio above the 0dB volume will likely always be distorted, therefore apply a 0dB limit to those devices.
