Shawn Guo 178c2490b9 thermal: step_wise: cdev only needs update on a new target state
The cooling device only needs update on a new target state.  Since we
already check old target in thermal_zone_trip_update(), we can do one
more check to see if it's a new target state.  If not, we can reasonably
save some uncecesary code execution.
