thermal: Don't use 'device' internal thermal zone structure field

Some drivers are directly using the thermal zone's 'device' structure
field.

Use the driver device pointer instead of the thermal zone device when
it is available.

Remove the traces when they are duplicate with the traces in the core
code.
