ARM: EXYNOS4: restart clocksource while system resumes
System resume can't be completed because mct-frc isn't restarted after system suspends. This patch restarts mct-frc during system resume. Reported-by: Jongpill Lee <boyko.lee@samsung.com> Signed-off-by: Changhwan Youn <chaos.youn@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
