ASoC: allo-piano-dac-plus: Remove pointless code

The codec control Digital Playback Volume is one of the controls deleted
by the allo-piano-dac-plus driver. It is effectively replaced by the
soundcard controls Master Playback Volume and Subwoofer Playback Volume.

Delete the code that sets the volume limit on those codec controls - the
limits on the soundcard volume controls are sufficient.
