[PATCHv4 6/9] ASoC: fsl-asoc-card: add use of devicetree TDM slot properties

Add use of optional TDM slot properties "dai-tdm-slot-num" and
"dai-tdm-slot-width" through snd_soc_of_parse_tdm_slot().
They allow setting a custom TDM slot width in bits and number of slots
for the CPU DAI when using the generic codec.
