** Description changed:
[ Impact ]
* To make thermald to support Intel PTL platform and support ITMT3
policy when it is present
[ Test Plan ]
* On Intel PTL platform with ITMT3.0 policy configured
* Boot into Ubuntu
* Stop the default thermald by $ sudo systemctl stop thermald
* run the thermlad with extra parameter $ sudo thermald --systemd
--dbus-enable --adaptive --log-level=info
* check the journalctl log to confirm that thermald apply the policy
successfully
1. Make sure to see ITMT3.0 policy defined in the APAT table

- added new ACPI device checking, only the platform equipped with Panther
Lake or later CPU should have the ACPI device, so that it won't introduce
regression.
+ If ITMT3 target present in the BIOS, system will go for ITMT policy
instead of the default passive policy setup.

https://github.com/intel/thermal_daemon/commit/03b4a139388f65f093277554ae5e025723320d28
enhance the support for the ITMT3.0 policy. No code logic change for
ITMT1.0 and ITMT2.0. For platform within ITMT3.0 configured, might
change the thermal behavior.
[ Other Info ]
- * Upstream commits:

+ workloads to them for increased single-threaded performance. This
+ technology assigns a higher priority to the fastest cores, ensuring that
+ demanding tasks get the maximum possible speed on those select cores,
+ while other cores handle less intensive work or remain idle.
