ALSA: hda: cs35l41: Remove cs35l41_hda_reg_sequence struct

Browse source 
Remove cs35l41_hd_reg_sequence as it adds a layer of flexibility not needed.
As cs35l41_hda_(start/stop)_bst is a single register, it can be replaced by
regmap_update_bits with usleep_range to wait for the same 3000us that
reg_sequence had.
