ASoC: fsl-asoc-card: Add slot_width setting for cpu-dai
ESAI may need to use fixed slot width to comply with external CODEC. So this set_tdm_slot() call will allow the ESAI driver to override its default dynamic slot width policy. Signed-off-by: Nicolin Chen <nicoleotsuka@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
