percpu: move generic {raw|this}_cpu_*_N() definitions to include/asm-generic/percpu.h
{raw|this}_cpu_*_N() operations are expected to be provided by archs
and the generic definitions are provided as fallbacks. As such, these
firmly belong to include/asm-generic/percpu.h.
Move the generic definitions to include/asm-generic/percpu.h. The
code is moved mostly verbatim; however, raw_cpu_*_N() are placed above
this_cpu_*_N() which is more conventional as the raw operations may be
used to defined other variants.
This is pure reorganization.
