Support set_trips() callback of thermal device ops. This allows HWMON device to operatively notify thermal core about temperature changes, which is very handy to have in a case where HWMON sensor is used by CPU thermal zone that performs passive cooling and emergency shutdown on overheat. Thermal core will be able to react faster to temperature changes. The set_trips() callback is entirely optional. If HWMON sensor doesn't support setting thermal trips, then the callback is a NO-OP. The dummy callback has no effect on the thermal core. The temperature trips are either complement the temperature polling mechanism of thermal core or replace the polling if sensor can set the trips and polling is disabled by a particular device in a device-tree.
