Pull power management fixes from Rafael Wysocki:
 "These fix two cpufreq issues, one introduced recently and one related
  to recent changes, fix cpufreq documentation, fix up recently added
  code in the Thunderbolt driver and update runtime PM framework
  documentation.

  Specifics:

   - Fix the handling of the scaling_cur_freq cpufreq policy attribute
     on x86 systems with the MPERF/APERF registers present to make it
     behave more as expected after recent changes (Rafael Wysocki).

   - Drop a leftover callback from the intel_pstate driver which also
     prevents the cpuinfo_cur_freq cpufreq policy attribute from being
     incorrectly exposed when intel_pstate works in the active mode
     (Rafael Wysocki).

   - Add a missing piece describing the cpuinfo_cur_freq policy
     attribute to cpufreq documentation (Rafael Wysocki).

   - Fix up a recently added part of the Thunderbolt driver to avoid
     aborting system suspends if its mailbox commands time out (Rafael
     Wysocki).

   - Update device runtime PM framework documentation to reflect the
     current behavior of the code (Johan Hovold)"
