Power management fixes for v4.10-rc8

Browse source 
- Add an intel_pstate driver quirk to work around a firmware setting
    that leads to frequency scaling issues on desktop Intel Kaby Lake
    processors in some configurations if the hardware-managed P-states
    (HWP) feature is in use (Srinivas Pandruvada).
 
  - Fix up the recently added brcmstb-avs cpufreq driver: fix a bug
    related to system suspend and change the sysfs interface to match
    the user space expectations (Markus Mayer).
 
  - Modify the runtime PM framework to avoid false-positive warnings
    from the might_sleep_if() assertions in it (Rafael Wysocki).

Pull power management fixes from Rafael Wysocki:
 "These add a quirk to intel_pstate to work around a firmware setting
  that leads to frequency scaling issues (discovered recently) on some
  Intel Kaby Lake processors, fix up the recently added brcmstb-avs
  cpufreq driver and avoid false-positive warnings from the runtime PM
  framework triggered by recent changes in i915.

  Specifics:
