Subject: [PATCH] wiphy: change wiphy_control_port_capable -> enabled

Move the reading of ControlPortOverNL80211 into wiphy itself and
renamed wiphy_control_port_capable to wiphy_control_port_enabled.
This makes things easier for any modules interested in control
port support since they will only have to check this one API rather
than read the settings and check capability.
