Changelog:

V5:
* Removed patch : "Move clock setup to pm.c"
* Added patch : "Move arm core power down clock to exynos5250 common code"
V4:
* Took into account Tomasz's comments
* Fixed missing call in for central suspend
* Passed parameter to the wakeup mask function
* Moved wakeup mask, boot vector and aftr state into a single
function
* Used this function as callback for platform data
* Moved S5P_CHECK_AFTR/S5P_CHECK_SLEEP into pm.c
* Set boot vector only one time
* Splitted some patches to make them more readable
V3:
* Added patch : "ARM: exynos: cpuidle: Disable cpuidle for 5440"
* Removed patch : "ARM: exynos: config: Enable cpuidle"
* Removed default ARM_EXYNOS4210_CPUIDLE=y
* Added comment about bug fix side effect 'for_each_possible_cpu'
V2:
* Added comment in changelog for calls order (5/17)
* Call the powerdown only for cpu0 in the pm notifier
* Set the pm notifier for all boards

V1: initial post

This patchset relies on the cpm_pm notifier to initiate the powerdown sequence
operations from pm.c instead cpuidle.c. Thus the cpuidle driver is no longer
dependent from arch specific code as everything is called from the pm.c file.

The patchset applies on top of linux-samsung/for-next.

Tested on exynos4: 4210
Tested on exynos5: 5250 (without AFTR)
