The arch/arm/mach-exynos4 directory (CONFIG_ARCH_EXYNOS4) has
made for plaforms based on EXYNOS4 SoCs. But since upcoming
Samsung's SoCs such as EXYNOS5 (ARM Cortex A15) can reuse most
codes in current mach-exynos4, one mach-exynos directory will
be used for them.

This patch changes to CONFIG_ARCH_EXYNOS (arch/arm/mach-exynos)
but keeps original CONFIG_ARCH_EXYNOS4 in mach-exynos/Kconfig to
avoid changing in driver side.

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.

This patch adds support System MMU which supports address transition
from virtual address to physical address. Basically, each hardware
block is connected System MMU block can use directly vitrual address
when it accesses physical memory not using physical address.
