Pisound Micro: Workaround for snd_soc_dai_set_tdm_slot with slots=0

Browse Source 
Even though it's documented that specifying slots=0 can be used to disable
the TDM mode, error checking introduced in 6.12.31 version broke this,
therefore, for the time being, a workaround is to provide a xlate_tdm_slot_mask
operation implementation to return 0 instead of -EINVAL as it does in case
slots argument is 0.
