[PATCH 2/5] ASoC: SDCA: Clean up error messages

[Charles Keepax <ckeepax@opensource.cirrus.com>]

All the error messages in the SDCA code manually print the function
in the output, update these to use dev_fmt instead. Whilst making
the changes tweak a couple of the error messages to make them a
little shorter.
