cfg80211: make regdom module parameter available oustide of OLD_REG

It seems a few users are using this module parameter although its not
recommended. People are finding it useful despite there being utilities
for setting this in userspace. I'm not aware of any distribution using
this though.

Until userspace and distributions catch up with a default userspace
automatic replacement (GeoClue integration would be nirvana) we copy
the ieee80211_regdom module parameter from OLD_REG to the new reg
code to help these users migrate.

Users who are using the non-valid ISO / IEC 3166 alpha "EU" in their
ieee80211_regdom module parameter and migrate to non-OLD_REG enabled
system will world roam.

This also schedules removal of this same ieee80211_regdom module
parameter circa March 2010. Hope is by then nirvana is reached and
users will abandoned the module parameter completely.
