Move the biquad channel names to a separate array and iterate over it in max98095_get_bq_channel rather than duplicating the hardcoded channel names. Add an error message if an invalid channel is passed and check the error in the callers. Also added a BUILD_BUG_ON to ensure that the bq_mode_name and controls arrays are the same size.
