Pull power management fixes from Rafael Wysocki:
 "These fix the device links support in runtime PM, correct mistakes in
  the cpuidle documentation, fix the handling of policy limits changes
  in the schedutil cpufreq governor, fix assorted issues in the OPP
  (operating performance points) framework and make one janitorial
  change.

  Specifics:

   - Unify the handling of managed and stateless device links in the
     runtime PM framework and prevent runtime PM references to devices
     from being leaked after device link removal (Rafael Wysocki).

   - Fix two mistakes in the cpuidle documentation (Julia Lawall).

   - Prevent the schedutil cpufreq governor from missing policy limits
     updates in some cases (Viresh Kumar).

   - Prevent static OPPs from being dropped by mistake (Viresh Kumar).

   - Prevent helper function in the OPP framework from returning
     prematurely (Viresh Kumar).

   - Prevent opp_table_lock from being held too long during removal of
     OPP tables with no more active references (Viresh Kumar).

   - Drop redundant semicolon from the Intel RAPL power capping driver
     (Tom Rix)"
