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.
