ASoC: wm8962: add .set_tdm_slot callback function

The slot_width can be different with the params_width(), for example,
DSP_A mode, slot_width = 32, but data format is S16_LE, if the word
length is configured to be 16, there is no sound on the right speaker.

So add .set_tdm_slot() callback function to configure the slot_width and
update the word length according to slot_width in hw_params().
