Bug description:
[Impact]
We have a couple dell and lenovo laptops which have dmic directly connected
to PCH, this needs intel sof driver to work, and intel sof driver is merged
oem-osp1-b kernel and it needs to load firmware and topology file to work.
[Fix]
Intel provides two binary files to us, one is firmware, the other is
topology file, these two files are built from
https://github.com/thesofproject/sof.git, and the license is BSD 3.
[Test Case]
put the firmware and topology to rootfs and boot with the oem-osp1-b
kernel on those machines, the sof driver works well.
[Regression Risk]
Low. just adding two new binary files, no change to existing files.
