percpu: reorder macros in percpu header files
* In include/asm-generic/percpu.h, collect {raw|_this}_cpu_generic*()
macros into one place. They were dispersed through
{raw|this}_cpu_*_N() definitions and the visiual inconsistency was
making following the code unnecessarily difficult.
* In include/linux/percpu-defs.h, move __verify_pcpu_ptr() later in
the file so that it's right above accessor definitions where it's
actually used.
This is pure reorganization.
