exynos cpuidle update for v3.17

Browse source 
- add callbacks exynos_suspend() and exynos_powered_up()
   for support cpuidle through mcpm
 - skip exynos_cpuidle for exynos5420 because is uses
   cpuidle-big-liggle generic cpuidle driver
 - add generic functions to calculate cpu number is used
   for pmu and this is required for exynos5420 multi-cluster
 - add of_device_id structure for big.LITTLE cpuidle and
   add "samsung,exynos5420" compatible string for exynos5420

------
In Linux 2.6.31+ the i386 kernel needs to run the mcelog utility
as a regular cronjob similar to the x86-64 kernel to process and log
machine check events when CONFIG_X86_NEW_MCE is enabled. Machine check
events are errors reported by the CPU. Processing them is strongly encouraged.
All x86-64 kernels since 2.6.4 require the mcelog utility to
process machine checks.
On x86 kernels the mcelog utility is needed to process and log machine check
