Bug description:
[Impact]
There is no sof-firmware for tgl platforms in the focal and groovy,
so the audio driver can't work on the tgl machines.
[Fix]
Intel released a firmware for tgl platforms, it is signed by
production key.
[Test Case]
Install the TGL_SOF_FW_prod_signed_v0.6.2_release to
/lib/firmware/intel/sof, boot the dell tgl machines, the sof driver
loads the sof-firmware successfully, and the audio driver works well
too.
[Regression Risk]
Low, this SRU adds new firmware, this firmware is only used by
intel tgl machines, and Intel told us this firmware is signed by
production key and is ok to release to ubuntu archive.
