wiphy: add wiphy_get_allowed_freqs

Browse Source 
This is more or less copied from scan_get_allowed_freqs but is
going to be needed by station (basically just saves the need for
station to do the same clone/constrain sequence itself).

One slight alteration is now a band mask can be passed in which
provides more flexibility for additional filtering.
