mac80211: allow mac80211 drivers to get to struct ieee80211_hw from wiphy
If a driver is given a wiphy and it wants to get to its private mac80211 driver area it can use wiphy_to_ieee80211_hw() to get first to its ieee80211_hw and then access the private structure via hw->priv. The wiphy_priv() is already being used internally by mac80211 and drivers should not use this. This can be helpful in a drivers reg_notifier(). Signed-off-by: Luis R.
