[PATCH v6 07/21] ASoC: fsl_micfil: drop error messages from failed register accesses

[Sascha Hauer]

Failed register accesses are really not expected in memory mapped
registers. When it fails then the register access itself is likely not
the reason, so no need to have extra error messages for each regmap
access. Just drop the error messages. This also fixes some places where
a return value is concatenated using 'ret |=' and then returned as
error value.
