drivers: thermal-core: Queue thermal zone update post suspend 



Thermal zone update for all the cores will happen in the post suspend
notifier context. This process can take a variable amount of time
depending upon the sensors that are read as a part of this.

To avoid delaying the system resume, queue the thermal zone device
update from the resume context.
