thermal: of-thermal: allow setting trip_temp on hardware
In current of-thermal, the .set_trip_temp only support to set trip_temp for SW. But some sensors support to set trip_temp on hardware, so that can trigger interrupt, shutdown or any other events. This patch adds .set_trip_temp() callback in thermal_zone_of_device_ops{}, so that the sensor device can use it to set trip_temp on hardware.
