ARM: EXYNOS: remove exynos4_scu_enable()
The exynos4_scu_enable() is a duplication of scu_enable(). Since commit '26a527e ARM: 7100/1: smp_scu: remove __init annotation from scu_enable()' makes scu_enable() available for non-init codes, exynos can directly call scu_enable() and save exynos4_scu_enable() now. Signed-off-by: Shawn Guo <shawn.guo@linaro.org> [kgene.kim@samsung.com: added missing header] Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
