I put this code to avoid overwrite BCLK value in TDM mode. BCLK is being configured by ' max98927_dai_tdm_slot'.
Now I added one more variable to check TDM mode instead of checking DAI_FMT.

OK. Thanks. But I kept if statement on the modified version because it only have two cases, tdm and non-tdm.
