Pull more ACPI and power management updates from Rafael Wysocki:
 "These are two reverts related to system suspend breakage by one of a
  recent commits, a fix for a recently introduced bug in devfreq and a
  bunch of other things that didn't make it into my previous pull
  request, but otherwise are ready to go.

  Specifics:

   - Revert two ACPI EC driver commits, one that broke system suspend on
     Acer Aspire S5 and one that depends on it (Rafael J Wysocki).

   - Fix a typo leading to an incorrect check in the exynos-ppmu devfreq
     driver (Dan Carpenter).

   - Add support for one more Broadwell CPU model to intel_idle (Len Brown).

   - Fix an obscure problem with state transitions related to interrupts
     in the speedstep-smi cpufreq driver (Mikulas Patocka).

   - Remove some unnecessary messages related to the "out of memory"
     condition from the core PM code (Quentin Lambert).

   - Update turbostat parameters and documentation, add support for one
     more Broadwell CPU model to it and modify it to skip printing
     disabled package C-states (Len Brown)"
