The sleep code for S5PV210 and EXYNOS4 are identical; moreover
S5p64X0 and S5PC100 for which support will be added soon can
use the same procedure. Create a common sleep code in the plat-s5p
directory so that it can be re-used.

Move the call to cpu_suspend into C code, and noticing that all the
s3c_cpu_save implementations are now identical, we can move this
into the common samsung code.

s3c_cpu_save does not need to save any registers with the new
cpu_suspend calling convention. Remove these redundant instructions.

cpu_suspend() has a weird calling method which makes it only possible to
call from assembly code: it returns with a modified stack pointer to
finish the suspend, but on resume, it 'returns' via a provided pointer.
We can make cpu_suspend() appear to be a normal function merely by
swapping the resume pointer argument and the link register.
Do so, and update all callers to take account of this more traditional
behaviour.

This patch adds support suspend to ram for EXYNOS4210.
As a note, this includes function of outer cache flush
because it is used before entering PM.
