Merge branch 'pm-cpufreq'

Merge cpufreq updates for 5.19-rc1:

 - Fix cpufreq governor clean up code to avoid using kfree() directly
   to free kobject-based items (Kevin Hao).

 - Prepare cpufreq for powerpc's asm/prom.h cleanup (Christophe Leroy).

 - Make intel_pstate notify frequency invariance code when no_turbo is
   turned on and off (Chen Yu).

 - Add Sapphire Rapids OOB mode support to intel_pstate (Srinivas
   Pandruvada).

 - Make cpufreq avoid unnecessary frequency updates due to mismatch
   between hardware and the frequency table (Viresh Kumar).

 - Make remove_cpu_dev_symlink() clear the real_cpus mask to simplify
   code (Viresh Kumar).

 - Rearrange cpufreq_offline() and cpufreq_remove_dev() to make the
   calling convention for some driver callbacks consistent (Rafael
   Wysocki).

 - Avoid accessing half-initialized cpufreq policies from the show()
   and store() sysfs functions (Schspa Shi).

 - Rearrange cpufreq_offline() to make the calling convention for some
   driver callbacks consistent (Schspa Shi).

 - Update CPPC handling in cpufreq (Pierre Gondois):

   * Add per_cpu efficiency_class to the CPPC driver.
   * Make the CPPC driver Register EM based on efficiency class
     information.
   * Adjust _OSC for flexible address space in the ACPI platform
     initialization code and always set CPPC _OSC bits if CPPC_LIB is
     supported.
   * Assume no transition latency if no PCCT in the CPPC driver.
   * Add fast_switch and dvfs_possible_from_any_cpu support to the CPPC
     driver.

* pm-cpufreq:
  cpufreq: CPPC: Enable dvfs_possible_from_any_cpu
  cpufreq: CPPC: Enable fast_switch
  ACPI: CPPC: Assume no transition latency if no PCCT
  ACPI: bus: Set CPPC _OSC bits for all and when CPPC_LIB is supported
  ACPI: CPPC: Check _OSC for flexible address space
  cpufreq: make interface functions and lock holding state clear
  cpufreq: Abort show()/store() for half-initialized policies
  cpufreq: Rearrange locking in cpufreq_remove_dev()
  cpufreq: Split cpufreq_offline()
  cpufreq: Reorganize checks in cpufreq_offline()
