Jongpill Lee a2fa3041b6 ARM: EXYNOS: Add Clock register list for save and restore 
This patch adds clock register list for save and restore. When system
enter suspend mode and wakeup from suspend mode, All clock register is
reset.  So critical register should be saved and reset.

[kgene.kim@samsung.com: re-worked on top of v3.4-rc7]
