Simplify cfg80211_chandef_compatible() a bit by switching c1 and c2 around so that c1 is always the narrower one (once they're not identical or narrow/S1G). Then we can just check the various primary channels and exit with the wider one (c2), or NULL. Also refactor the primary 40/80/160 function to not have all the calculations hard-coded, and use a wrapper around it to check primary 40/80/160 compatibility. While at it, add some kunit tests for this functionality. Also expose the new cfg80211_chandef_primary_freq() to drivers, mac80211 will use it.
