Region code support

[Sebastian Andrzej Siewior]

I need the ability to change the region code because the default region
does not work. This was supported by ipwpriv until 2.6.22 and is still
mention in the olpc wiki [0]. So the suported is gone via 7dcf5284d1
("[PATCH] libertas: remove private ioctls") with no replacement afaik.

As far as I can see the only way is to port the driver to cfg80211 which
brings the regulatory support [1].

Is there something I've overseen?
