When that is done, no get_trip_* ops are needed and they can be removed. The get_trip_temp, get_trip_hyst and get_trip_type are handled by the get_trip_point(). The set_trip_temp() generic function does some checks which are no longer needed in the set_trip_point() ops. Convert ops content logic into generic trip points and register them with the thermal zone.
