Subject: [PATCH v2 16/20] hda: cs35l41: Reorganize log for playback actions

For each case, only log the last regmap access
so it doesn't get overwritten, and all regmap
access should show the same issues.
Change to dev_err to log this error.

Also, differentiate between a regmap access
failure and invalid playback action.
