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).

* acpi-processor:
  ACPI: processor: idle: Remove redundant pr->power.count assignment
  ACPI: processor: idle: Set pr->flags.power unconditionally
  ACPI: processor: idle: Remove obsolete comment

* acpi-cppc:
  ACPI: CPPC: Add three functions related to autonomous selection
  ACPI: CPPC: Modify cppc_get_auto_sel_caps() to cppc_get_auto_sel()
  ACPI: CPPC: Refactor register value get and set ABIs
  ACPI: CPPC: Add cppc_set_reg_val()
  ACPI: CPPC: Extract cppc_get_reg_val_in_pcc()
  ACPI: CPPC: Rename cppc_get_perf() to cppc_get_reg_val()
  ACPI: CPPC: Optimize cppc_get_perf()
  ACPI: CPPC: Add IS_OPTIONAL_CPC_REG macro to judge if a cpc_reg is optional
  ACPI: CPPC: Simplify PCC shared memory region handling
  ACPI: PCC: Simplify PCC shared memory region handling
