cfg80211: move regulatory flags to their own variable

We'll expand this later, this will make it easier to
classify and review what things are related to regulatory
or not.

Coccinelle only missed 4 hits, which I had to do manually,
supplying the SmPL in case of merge conflicts.

+ *	only allow further regulatory domain settings to further enhance
