Intel released a new version of sof firmware to Canonical, and in this
new version there are 3 major changes:
 - fix the hang issue in the firmware for the cml and cnl
 - introduce the ldc file which helps to do the firmware debug
 - divide the firmware to cml and cnl specific ones

And Intel suggested that we should integrate the version v1.3-0f73628
and only integrate the firmware for cnl and cml, since like those apl
cht and icl firmwares, they are not fully tested yet.

We have a couple of Dell machines, after installing the system, the
system will hang randomly. After disabling the sof driver, it will not
hang anymore.

Intel help to debug this issue, and finally provide this new firmware
to us, and we tested this firmware can fix the hang issue.

The source code for this firmware is located at:
https://github.com/thesofproject/sof.git

And this firmware is generated based on the sof.git and is
signed with Intel production key.

Intel wrote a new sound driver to make the digital microphone work,
most of the kernel driver is merged to kernel-v5.2, and Intel
already helped us to backport the sof driver to oem-osp1-b kernel.

To make the sof driver work, it also needs to load the correct firmware
and topology file, these two binary files are built from sof
repository which is located at:
https://github.com/thesofproject/sof.git

The license of this repository is "BSD 3" and Intel told us it is
OK for us to integrate these two files to ubunut linux-firmware
first, and Intel plans to upstream these two files to mainline
linux-firmware too in the near future.

And these two files are built based on the commit 6cc8da10 of
https://github.com/thesofproject/sof.git. Intel called it is
PV release for the sof driver, firmware and topology.
