Simplify the parameters by extending the thermal_zone_device_param structure with the parameters usually used when registering the thermal zone. With that change we have a simpler function: thermal_zone_device_register() which can be reused in the different drivers and replace the duplicate thermal_zone_device_register_with_trips() and thermal_zone_device_register_tripless() functions.
