ASoC: mxs: Improve probe error handling

bui duc phuc <phucduc.bui@gmail.com> says:

This series improves probe error handling in the MXS ASoC drivers.
Use dev_err_probe() where appropriate and remove redundant dev_err() calls
when the corresponding errors are already reported by the called functions
or further down the call chain.

Compile-tested only.
