ASoC: Intel: skl_hda_dsp_generic: add DMIC support
Add dmic dai links using naming conventions used in
previous machine drivers.
Tested on whiskylake & icelake with SOF driver. Due
to a missing topology file, the DMIC functionality
could not be tested with the Skylake driver but was
tested for non-regressions on a GeminiLake platform
without DMICs.
