percpu: introduce arch_raw_cpu_ptr()
Currently, archs can override raw_cpu_ptr() directly; however, we
wanna build a layer of indirection in the generic part of percpu so
that we can implement generic features there without affecting archs.
Introduce arch_raw_cpu_ptr() which is used to define raw_cpu_ptr() by
generic percpu code. The two are identical for now. x86 is currently
the only arch which overrides raw_cpu_ptr() and is converted to
define arch_raw_cpu_ptr() instead.
This doesn't introduce any functional difference.
