Keep all power-domains already enabled by bootloader on, even if no
driver has claimed them. This is useful for debug and development, but
should not be needed on a platform with proper driver support.

Pull more ACPI and power management updates from Rafael Wysocki:
 "These are commits that were not quite ready when I sent the original
  pull request for 3.15-rc1 several days ago, but they have spent some
  time in linux-next since then and appear to be good to go.  All of
  them are fixes and cleanups.

  Specifics:

   - Remaining changes from upstream ACPICA release 20140214 that
     introduce code to automatically serialize the execution of methods
     creating any named objects which really cannot be executed in
     parallel with each other anyway (previously ACPICA attempted to
     address that by aborting methods upon conflict detection, but that
     wasn't reliable enough and led to other issues).  From Bob Moore
     and Lv Zheng.

   - intel_pstate fix to use del_timer_sync() instead of del_timer() in
     the exit path before freeing the timer structure from Dirk
     Brandewie (original patch from Thomas Gleixner).

   - cpufreq fix related to system resume from Viresh Kumar.

   - Serialization of frequency transitions in cpufreq that involve
     PRECHANGE and POSTCHANGE notifications to avoid ordering issues
     resulting from race conditions.  From Srivatsa S Bhat and Viresh
     Kumar.

   - Revert of an ACPI processor driver change that was based on a
     specific interpretation of the ACPI spec which may not be correct
     (the relevant part of the spec appears to be incomplete).  From
     Hanjun Guo.

   - Runtime PM core cleanups and documentation updates from Geert
     Uytterhoeven.

   - PNP core cleanup from Michael Opdenacker"

This patch adds cpufreq suspend/resume calls to dpm_{suspend|resume}()
for handling suspend/resume of cpufreq governors.

Lan Tianyu (Intel) & Jinhyuk Choi (Broadcom) found an issue where the
tunables configuration for clusters/sockets with non-boot CPUs was
lost after system suspend/resume, as we were notifying governors with
CPUFREQ_GOV_POLICY_EXIT on removal of the last CPU for that policy
which caused the tunables memory to be freed.

This is fixed by preventing any governor operations from being
carried out between the device suspend and device resume stages of
system suspend and resume, respectively.

We could have added these callbacks at dpm_{suspend|resume}_noirq()
level, but there is an additional problem that the majority of I/O
devices is already suspended at that point and if cpufreq drivers
want to change the frequency before suspending, then that not be
possible on some platforms (which depend on peripherals like i2c,
regulators, etc).
