thermal/drivers/uniphier: Use generic thermal_zone_get_trip() function
The thermal framework gives the possibility to register the trip
points with the thermal zone. When that is done, no get_trip_* ops are
needed and they can be removed.
Convert ops content logic into generic trip points and register them with the
thermal zone.
