wireless: remove struct regdom hinting
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 a driver is providing the hint this is the driver's very
- * own &struct wiphy
+ * @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.
