Pull power management updates from Rafael Wysocki:
 "The amd-pstate cpufreq driver gets the majority of changes this time.
  They are mostly fixes and cleanups, but one of them causes it to
  become the default cpufreq driver on some AMD server platforms.

  Apart from that, the menu cpuidle governor is modified to not use
  iowait any more, the intel_idle gets a custom C-states table for
  Granite Rapids Xeon D, and the intel_pstate driver will use a more
  aggressive Balance- performance default EPP value on Granite Rapids
  now.

  There are also some fixes, cleanups and tooling updates.

  Specifics:

   - Update the amd-pstate driver to set the initial scaling frequency
     policy lower bound to be the lowest non-linear frequency (Dhananjay
     Ugwekar)

   - Enable amd-pstate by default on servers starting with newer AMD
     Epyc processors (Swapnil Sapkal)

     S. Bae)

   - Ensure sugov_eas_rebuild_sd() is always called when sugov_init()

     to be enabled (Christian Loehle)
