cfg80211: enable 5 GHz world roaming channels
The current static world regulatory domain is too restrictive, we can use some 5 GHz channels world wide so long as they do not touch frequencies which require DFS. The compromise is we must also enforce passive scanning and disallow usage of a mode of operation that beacons: (AP | IBSS | Mesh) Signed-off-by: Luis R.
