[PATCH v1 15/16] thermal: core: Drop the .throttle() governor callback

Rafael J. Wysocki

From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

Since all of the governors in the tree have been switched over to using
the new callbacks, either .trip_crossed() or .manage(), the .throttle()
governor callback is not used any more, so drop it.
