thermal: gov_user_space: Use .trip_crossed() instead of .throttle()
Notifying user space about trip points that have not been crossed is
not particularly useful, so modify the User Space governor to use the
.trip_crossed() callback, which is only invoked for trips that have been
crossed, instead of .throttle() that is invoked for all trips in a
thermal zone every time the zone is updated.
