Srinivas Pandruvada 52f04f10b9 thermal: intel: int340x: processor_thermal: Fix deadlock
When user space updates the trip point there is a deadlock, which results
in caller gets blocked forever.

Commit 05eeee2b51 ("thermal/core: Protect sysfs accesses to thermal
operations with thermal zone mutex"), added a mutex for tz->lock in the
function trip_point_temp_store(). Hence, trip set callback() can't
call any thermal zone API as they are protected with the same mutex lock.

The callback here calling thermal_zone_device_enable(), which will result
in deadlock.

Move the thermal_zone_device_enable() to proc_thermal_pci_probe() to
avoid this deadlock.
