ASoC: Intel: sof_sdw: add mic:dmic and cfg-mics component strings
UCM needs to know which microphone is used (dmic or RT715-based), let's add the information in the component string. Note the slight change from HDAudio platforms where 'cfg-dmics' was used. 'cfg-mics' is used here with the intent that this component string describes either the number of PCH-attached microphones or the number of RT715-attached ones (the assumption is that the two configurations are mutually exclusive).
