ACPI and power management fixes for 3.17-rc5

Browse Source 
- Fix for the cpufreq Operation Performance Points (OPP) code
    where a recent commit added a kcalloc() call with an incorrect
    ordering of arguments.  From Anand Moon.
 
  - Reverts of two ACPI battery commits that caused incorrect
    diagnostic information to be printed to dmesg in some cases
    from Bjørn Mork.
 
  - Fix for the ACPI RTC operation region handler that applied the
    & operator to an argument already representing an address and
    that caused it to overwrite its own argument instead of writing
    to the address contained in it as expected.  From Chun-Yi Lee.
 
  - Fix for the PM domain implementation in the ACPI LPSS (Low-Power
    Subsystem) driver where one callback pointer pointed to a wrong
    routine and one was NULL, but it shouldn't.  From Fu Zhonghui.

Pull ACPI and power management fixes from Rafael Wysocki:
 "These are regression fixes (cpufreq, ACPI battery) and fixes for stuff
  that never worked correctly (ACPI RTC operation region handler and PM
  domain implementation in the ACPI LPSS driver).

  Specifics:

   - Fix for the cpufreq Operation Performance Points (OPP) code where a
     recent commit added a kcalloc() call with an incorrect ordering of
     arguments.  From Anand Moon.

   - Reverts of two ACPI battery commits that caused incorrect
     diagnostic information to be printed to dmesg in some cases from
     Bjørn Mork.

   - Fix for the ACPI RTC operation region handler that applied the &
     operator to an argument already representing an address and that
     caused it to overwrite its own argument instead of writing to the
     address contained in it as expected.  From Chun-Yi Lee.

   - Fix for the PM domain implementation in the ACPI LPSS (Low-Power
     Subsystem) driver where one callback pointer pointed to a wrong
     routine and one was NULL, but it shouldn't.  From Fu Zhonghui"
