[Resend 2x] thermal: Prevent polling from happening during system suspend

["Rafael J. Wysocki" <rjw@sisk.pl>]

From: Rafael J. Wysocki <rjw@sisk.pl>

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.
