Please refer to https://www.alsa-project.org/main/index.php/Firmware
as the driver and the firmware should be distributed by the
ALSA-Project. We are the maintainers of the Debian ALSA packages and
provide ALSA to users.

As far as i can see you need a driver which
is part of the kernel. Putting the firmware in
lib/firmware/intel/sof should be the right way. If you succeeded and
have a running alsa system on your device the only thing you can do
is to ask the Debian kernel maintainers to include the firmware in
our firmware packaging and enable your driver in the kernel
distributed by Debian.
