ARM: EXYNOS: add support get_core_count() for EXYNOS5250
The EXYNOS5250 has two Cortex-A15 cores and there's no need to call scu_enable() in platform_smp_prepare_cpus() because Cortex-A15 has no regarding scu register which can be used for getting number of cores. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
