Merge branches 'acpi-processor' and 'acpi-cppc'

Merge ACPI processor driver updates and ACPI CPPC library updates for
6.16-rc1:

 - Clean up the initialization of CPU data structures in the ACPI
   processor driver (Zhang Rui).

 - Remove an obsolete comment regarding the C-states handling in the
   ACPI processor driver (Giovanni Gherdovich).

 - Simplify PCC shared memory region handling (Sudeep Holla).

 - Rework and extend functions for reading CPPC register values and for
   updating CPPC registers (Lifeng Zheng).

 - Add three functions related to autonomous CPU performance state
   selection to the CPPC library (Lifeng Zheng).
