thermal: Prevent polling from happening during system suspend 

The thermal driver should use a freezable workqueue to schedule
polling to prevent thermal_zone_device_update() from being run
during system suspend, when the devices it relies on may be inactive.
Make it use the system freezable workqueue for this purpose.
