Sorry for late, many mails had been discard by my outlook, including the
Last one.

@Mark, @Lars,

This adds the function of snd_soc_dai_set_tdm_slot_xlate, which is almost
One new signature of snd_soc_dai_set_tdm_slot discarding the mask
Parameters, which could be generated by itself.

And I want to provide one standard method for the drivers who are parsing
The TDM information from the DT node.
