Subject: [PATCH v7 11/29] 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.
