ASoC: max98088: Remove duplicate DACs

This codec only has one set of left and right DACs, remove the duplicate
DACs with duplicated bits controlling them as the userspace can set those
controls to mismatched value. This most likely does break userspace ABI,
but there seem to be no in-kernel users.
