wireless: don't publish __regulatory_hint

Browse source 
This function requires an internal lock to be held, so it cannot
be published to other modules in the kernel.

* of world roaming but wants to respect its own EEPROM mappings for
* specific regulatory domains it should register the @reg_notifier callback
* on the &struct wiphy. Returns 0 if the hint went through fine or through an
* intersection operation. Otherwise a standard error code is returned.
