cfg80211: treat ieee80211_regdom hints as user hints
We were treating ieee80211_regdom module parameter hints as core hints, this means we were not letting the user help compliance further when using the module parameter. It also meant that users with a device with a custom regulatory domain set (wiphy->custom_regulatory) using this module parameter were being stuck to the original default core static regualtory domain. We fix this by using the static cfg80211_regdomain alpha2 as the core hint and treating the module parameter separately. All iwlwifi and ath5k/ath9k/ar9170 devices which world roam set the wiphy->custom_regulatory. This change allows users using this module parameter to have it trated as a a proper user hint and not have it ignored. Signed-off-by: Luis R.
