More power management updates for v4.11-rc1

- Fix for a cpuidle menu governor problem that started to take an
    unnecessary spinlock after one of the recent updates and that
    did not play well with the RT patch (Rafael Wysocki).
 
  - Fix for the new intel_pstate operation mode switching feature
    added recently that did not reinitialize P-state limits properly
    when switching operation modes (Rafael Wysocki).
 
  - Removal of unused global notifiers from the PM QoS framework
    (Viresh Kumar).
 
  - Generic power domains framework update to make it handle
    asynchronous invocations of PM callbacks in the "noirq" phases
    of system suspend/hibernation correctly (Ulf Hansson).
 
  - Two hibernation core cleanups (Rafael Wysocki).
 
  - intel_idle cleanup related to the sysfs interface (Len Brown).
 
  - Off-by-one bug fix in the OPP (Operating Performance Points)
    framework (Andrzej Hajda).
 
  - OPP framework's documentation fix (Viresh Kumar).
 
  - cpufreq qoriq driver cleanup (Tang Yuantian).
 
  - Fixes for typos in comments in the device runtime PM framework
    (Christophe Jaillet).

 "These fix two bugs introduced by recent power management updates (in
  the cpuidle menu governor and intel_pstate) and a few other issues,
  clean up things and remove unused code.

  Specifics:

   - Fix for a cpuidle menu governor problem that started to take an
     unnecessary spinlock after one of the recent updates and that did
     not play well with the RT patch (Rafael Wysocki).

   - Fix for the new intel_pstate operation mode switching feature added
     recently that did not reinitialize P-state limits properly when
     switching operation modes (Rafael Wysocki).

   - Removal of unused global notifiers from the PM QoS framework
     (Viresh Kumar).

   - Generic power domains framework update to make it handle
     asynchronous invocations of PM callbacks in the "noirq" phases of
     system suspend/hibernation correctly (Ulf Hansson).

   - Two hibernation core cleanups (Rafael Wysocki).

   - intel_idle cleanup related to the sysfs interface (Len Brown).

   - Off-by-one bug fix in the OPP (Operating Performance Points)
     framework (Andrzej Hajda).

   - OPP framework's documentation fix (Viresh Kumar).

   - cpufreq qoriq driver cleanup (Tang Yuantian).
