As slots and slot_width can be set manually using set_tdm(). These values are then kept in sun4i_i2s struct. So we need to check if these values are setted or not in the struct.
Avoid to check for this logic in set_chan_cfg(). This will duplicate the same check instead pass the required values as params to set_chan_cfg().
This will also avoid a bug when we will enable 20/24bits support, i2s->slot_width is not actually used in the lrck_period computation.
