[PATCH] ASoC: tlv320aic32x4: Fix TAS2505 volume controls

[Marek Vasut]

None of the TAS2505 outputs are stereo, do not pretend they are by
implementing them using SOC*DOUBLE* macros referencing the same
register twice, use SOC*SINGLE* instead. Fix volume ranges and mute
control for the codec according to datasheet.
