So far, only OEM-B-OSP1, EOAN and later kernels have the alsa/sof driver,
and the OEM-B-OSP1 kernel already enabled these CONFIGs.
[Impact]
We tested the EOAN kernel on the LENOVO or Dell machines which have
dmic directly connnected to PCH, the dmic didn't work.
[Fix]
We need to enable SOF_HDA link and codec, then the sof driver
and Legacy HDA driver work together to make the dmic work.
[Test Case]
Install the latest 19.10 image, build a new kernel with this
patch and replace the existing kernel, After installing the blacklist
package (blacklist snd_hda_intel and snd_soc_skl) and ucm package,
the dmic and all output devices (speaker/hdmi) work.
[Regression Risk]
Low, these configs are already enabled in the oem-b-osp1 kernel
for a long time, and we tested it on many lenovo/dell machines witch
have or have no dmic, all worked well.
