Merge branches 'pm-cpuidle' and 'pm-cpufreq'

Merge CPU power management updates for 6.6-rc1:

 - Rework the menu and teo cpuidle governors to avoid calling
   tick_nohz_get_sleep_length(), which is likely to become quite
   expensive going forward, too often and improve making decisions
   regarding whether or not to stop the scheduler tick in the teo
   governor (Rafael Wysocki).

 - Improve the performance of cpufreq_stats_create_table() in some
   cases (Liao Chang).

 - Fix two issues in the amd-pstate-ut cpufreq driver (Swapnil Sapkal).

 - Use clamp() helper macro to improve the code readability in
   cpufreq_verify_within_limits() (Liao Chang).

 - Set stale CPU frequency to minimum in intel_pstate (Doug Smythies).

* pm-cpuidle:
  cpuidle: teo: Avoid unnecessary variable assignments
  cpuidle: menu: Skip tick_nohz_get_sleep_length() call in some cases
  cpuidle: teo: Gather statistics regarding whether or not to stop the tick
  cpuidle: teo: Skip tick_nohz_get_sleep_length() call in some cases
  cpuidle: teo: Do not call tick_nohz_get_sleep_length() upfront
  cpuidle: teo: Drop utilized from struct teo_cpu
  cpuidle: teo: Avoid stopping the tick unnecessarily when bailing out
  cpuidle: teo: Update idle duration estimate when choosing shallower state

* pm-cpufreq:
  cpufreq: amd-pstate-ut: Fix kernel panic when loading the driver
  cpufreq: amd-pstate-ut: Remove module parameter access
  cpufreq: Use clamp() helper macro to improve the code readability
  cpufreq: intel_pstate: set stale CPU frequency to minimum
  cpufreq: stats: Improve the performance of cpufreq_stats_create_table()
