ARM: EXYNOS4: Move S5P_CENTRAL_SEQ_CONFIGURATION setting for PM
We need to balance between set and check S5P_CENTRAL_SEQ_CONFIGURATION register in syscore_ops suspend/resume function when failure in enter suspend mode. Moved this register setting for PM for the purpose of balancing. Signed-off-by: Jaecheol Lee <jc.lee@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
