I think the first order would be to have the file cleaned-up, with its Intel origin clearly stated with a signed-off-by tag.
Then once this is done, the Debian package creation needs to be handled (using either the ALSA repo or the cloned version on SOF GitHub). I don't have any experience with Debian packages so can't really comment on the effort it would take.
I did some cleanups here:

Pierre, could you confirm the original source and are you ok with that?
I got confirmation from Intel that they are the original source - they provided me with the files (as an aside in case it is important, originally they were working with Canonical on getting Ubuntu working on one of our (Lenovo) platforms). I was following up with Canonical to just check what they had done but haven't heard back yet.
Since Intel has provided the files to me directly - can I act as an original source confirmation?
