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.

As PHYS_OFFSET will be becoming a variable, we can't have it used in
initializers nor assembly code.  Replace those in generic code with
a run-time initialization.  Replace those in platform code using the
individual platform specific PLAT_PHYS_OFFSET.
