This patch fixes the way of comparison for handling of two or more
clock sources for UART.
For example, if just only one clock source is defined even though
there are two clock sources for UART, the serial driver does not
set proper clock up. Of course, it is problem.
So this patch changes the condition of comparison to avoid useless
setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means
selection of source clock is not required.
In addition, since the Exynos4210 has only one clock source for UART
this patch adds the flag into its common_init_uarts().

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.
