wireless: remove struct regdom hinting

Browse Source 
The code needs to be split out and cleaned up, so as a
first step remove the capability, to add it back in a
subsequent patch as a separate function. Also remove the
publically facing return value of the function and the
wiphy argument. A number of internal functions go from
being generic helpers to just being used for alpha2
setting.

* __regulatory_hint - hint to the wireless core a regulatory domain

* @wiphy: if the hint comes from country information from an AP, this
* is required to be set to the wiphy that received the information
* @alpha2: the ISO/IEC 3166 alpha2 being claimed the regulatory domain
* should be in. If @rd is set this should be NULL
* @rd: a complete regulatory domain, if passed the caller need not worry
* about freeing it
* should be in.
*
* The Wireless subsystem can use this function to hint to the wireless core
* what it believes should be the current regulatory domain by
* giving it an ISO/IEC 3166 alpha2 country code it knows its regulatory
* domain should be in or by providing a completely build regulatory domain.
* domain should be in.
*
* Returns -EALREADY if *a regulatory domain* has already been set. Note that
* this could be by another driver. It is safe for drivers to continue if
* -EALREADY is returned, if drivers are not capable of world roaming they
* should not register more channels than they support. Right now we only
* support listening to the first driver hint. If the driver is capable
* 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.
* Returns zero if all went fine, %-EALREADY if a regulatory domain had
* already been set or other standard error codes.
