Pull power management fix from Rafael Wysocki:
 "Fix a relatively old initialization issue in intel_pstate causing the
  pcc-cpufreq driver to be used instead of it on some HP Proliant
  systems.

  This turned into a functional regression during the 4.17 cycle,
  because pcc-cpufreq is a scalability disaster and that was amplified
  by the idle loop rework done at that time (Rafael Wysocki).
