[alsa-devel] [PATCH 2/4] Revert "ASoC: twl4030: Use core to set the msbits constraint"

The core implementation applies the msbits constraint to samples
where it should not.
Do not ask core to do this, the original code does the right thing.

This reverts commit f3da57f0fc092d338fe83cf89e3fe25ca2283bbf.
