Merge branch 'thermal-intel'

Merge thermal control changes related to Intel platforms for 6.3-rc1:

 - Rework ACPI helper functions for thermal control to retrieve a trip
   point temperature instead of initializing a trip point objetc (Rafael
   Wysocki).

 - Clean up and improve the int340x thermal driver ((Rafael Wysocki).

 - Simplify and clean up the intel_pch thermal driver ((Rafael Wysocki).

 - Fix the Intel powerclamp thermal driver and make it use the common
   idle injection framework (Srinivas Pandruvada).

 - Add two module parameters, cpumask and max_idle, to the Intel powerclamp
   thermal driver to allow it to affect only a specific subset of CPUs
   instead of all of them (Srinivas Pandruvada).

 - Make the Intel quark_dts thermal driver Use generic trip point
   objects instead of its own trip point representation (Daniel
   Lezcano).

 - Add toctree entry for thermal documents and fix two issues in the
   Intel powerclamp driver documentation (Bagas Sanjaya).
