That Kconfig option seems unnecessary - after all, the regulatory
database still has a say in this?

Even the NL80211_RRF_ITSG5 flag seems somewhat unnecessary - if the
regulatory database did in fact provide information on these channels,
then we can assume they're usable, no?

IOW - I don't really see the point of this patch - can't we treat these
channels just like regular ones, and rely on the regulatory information
to prevent their use in all but special scenarios (where the integrator
is providing a proper database)?
