ASoC: SOF: sof-audio: add sof_dai_get_tdm_slots function
An new interface, sof_dai_get_tdm_slots(), is added for machine driver to get tdm slot number from topology. The dai_get_param() callback needs to support new parameter type SOF_DAI_PARAM_INTEL_SSP_TDM_SLOTS by returning the tdm slot number of specific SSP port.
