e7089da956 ARM: pm: samsung: move cpu_suspend into C code
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.

769783a930 ARM: pm: mach-exynos4: cleanup s3c_cpu_save
s3c_cpu_save does not need to save any registers with the new
cpu_suspend calling convention.  Remove these redundant instructions.

e8856a8797 ARM: pm: convert cpu_suspend() to a normal function
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.
