ARM: EXYNOS4: Add EXYNOS4 CPU initialization support
This patch adds EXYNOS4 CPU support files in mach-exynos4, and basically they are moved from mach-s5pv310 so that it can support Samsung's new CPU name, EXYNOS4. The EXYNOS4 ingegrates a ARM Cortex A9 multi-core. Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
