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.

This patch applies on top of linux-pm/linux-next
V2:
- Changed get_trip_temp() to return THERMAL_TEMP_INVALID
- Register unconditonnaly the thermal trips
- Fixed thermal_zone_device_register() call replaced by the
_with_trips() version
