Subject: ASoC: ssm4567: Keep TDM_BCLKS in ssm4567_set_dai_fmt
commit a6c2a32ac83567f15e9af3dcbc73148ce68b2ced upstream.
The regmap_write in ssm4567_set_dai_fmt accidentally clears the
TDM_BCLKS field which was set earlier by ssm4567_set_tdm_slot.
This patch fixes it by using regmap_update_bits with proper mask.
