Bug description:
[Impact]
When booting our 20.04 + oem-5.6 kernel on tgl platforms, the sof
audio driver always fails to load the sof firmware, the audio function
deosn't work at all on tgl platforms.
[Fix]
Intel released sof-firmware including tplg for tgl platforms, after
putting them in the /lib/firmware/inte/sof|sof-tplg, the audio works
well on those tgl platforms.
[Test Case]
Put those firmware and tplg to linux-firmware folders, boot 20.04
+ oem-5.6 kernel on tgl platforms, the audio works well.
[Regression Risk]
Low, just adding some new files, no change on existing files.
