thermal: Fix build for Linux v6.10

Browse Source 
In Linux v6.10, commit b1ae92dcfa8e ("thermal: core: Make struct
thermal_zone_device definition internal") made the structure
'thermal_zone_device' internal and so the 'devdata' member is no longer
directly accessible. The function thermal_zone_device_priv() was added
in Linux v6.4 for retrieving the 'devdata' and so update the various
thermal drivers to use this function if present.
