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 - driver hint to the wireless core a regulatory domain
- * @wiphy: the driver's very own &struct wiphy
+ * @wiphy: the wireless device giving the hint (used only for reporting
+ *      conflicts)
  * @alpha2: the ISO/IEC 3166 alpha2 the driver claims its regulatory domain
  *      should be in. If @rd is set this should be NULL. Note that if you
  *      set this to NULL you should still set rd->alpha2 to some accepted
  *      alpha2.
- * @rd: a complete regulatory domain provided by the driver. If passed
- *      the driver does not need to worry about freeing it.
  *
  * Wireless drivers 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.
  * If the driver provides an ISO/IEC 3166 alpha2 userspace will be queried
- * for a regulatory domain structure for the respective country. If
- * a regulatory domain is build and passed you should set the alpha2
- * if possible, otherwise set it to the special value of "99" which tells
- * the wireless core it is unknown.
- *
- * 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.
+ * for a regulatory domain structure for the respective country.
