ACPI and power management fixes for 3.17-rc7

 - Revert of a recent hibernation core commit that introduced
   a NULL pointer dereference during resume for at least one user
   (Rafael J Wysocki).

 - Fix for the ACPI LPSS (Low-Power Subsystem) driver to disable
   asynchronous PM callback execution for LPSS devices during system
   suspend/resume (introduced in 3.16) which turns out to break
   ordering expectations on some systems.  From Fu Zhonghui.

 - cpufreq core fix related to the handling of sysfs nodes during
   system suspend/resume that has been broken for intel_pstate
   since 3.15 from Lan Tianyu.

 - Restore the generation of "online" uevents for ACPI container
   devices that was removed in 3.14, but some user space utilities
   turn out to need them (Rafael J Wysocki).

 - The cpufreq core fails to release a lock in an error code path
   after changes made in 3.14.  Fix from Prarit Bhargava.

 - ACPICA and ACPI/GPIO fixes to make the handling of ACPI GPIO
   operation regions (which means AML using GPIOs) work correctly
   in all cases from Bob Moore and Srinivas Pandruvada.

 - Fix for a wrong sign of the ACPI core's create_modalias() return
   value in case of an error from Mika Westerberg.

 - ACPI backlight blacklist entry for ThinkPad X201s from Aaron Lu.
