cfg80211: make regulatory_hint() remove REGULATORY_CUSTOM_REG

The REGULATORY_CUSTOM_REG can be used during early init with
the goal of overriding the wiphy's default regulatory settings
in case the alpha2 of the device is not known. In the case that
the alpha2 becomes known lets avoid having drivers having to
clear the REGULATORY_CUSTOM_REG flag by doing it for them
when regulatory_hint() is used.
