ASoC: fsl_ssi: Fix TDM slot setup for I2S mode
commit 87263968516fb9507d6215d53f44052627fae8d8 upstream.
When using the driver in I2S TDM mode, the _fsl_ssi_set_dai_fmt()
function rewrites the number of slots previously set by the
fsl_ssi_set_dai_tdm_slot() function to 2 by default.
To fix this, let's use the saved slot count value or, if TDM
is not used and the slot count is not set, proceed as before.
