ACPI and power management fixes for 3.14-rc3

- Fix for a recent regression in the intel_pstate driver that
    introduced a race condition causing systems to crash during
    initialization in some situations.  This removes the affected
    code altogether.  From Dirk Brandewie.
 
  - ACPIPHP fix for a regression introduced during the 3.12 cycle
    causing devices to be dropped as a result of bus check notifications
    after system resume on some systems due to the way ACPIPHP interprets
    _STA return values (arguably incorrectly).  From Mika Westerberg.
 
  - ACPI dock driver fix for a problem causing docking to fail due to
    a check that always fails after recent ACPI core changes (found by
    code inspection).
 
  - ACPI container driver fix to prevent memory from being leaked in
    an error code path after device_register() failures.
 
  - Update of the arm_big_little cpufreq driver maintainer's e-mail
    address.

Pull ACPI and power management fixes from Rafael Wysocki:
 "These include a fix for a recent intel_pstate regression, a fix for a
  regression in the ACPI-based PCI hotplug (ACPIPHP) code introduced
  during the 3.12 cycle, fixes for two bugs in the ACPI core introduced
  recently and a MAINTAINERS update related to cpufreq.

  Specifics:

   - Fix for a recent regression in the intel_pstate driver that
     introduced a race condition causing systems to crash during
     initialization in some situations.  This removes the affected code
     altogether.  From Dirk Brandewie.
