powerpc/ftrace: Add support for livepatch to PPC32
PPC64 needs some special logic to properly set up the TOC.
See commit 85baa095497f ("powerpc/livepatch: Add live patching support
on ppc64le") for details.
PPC32 doesn't have TOC so it doesn't need that logic, so adding
LIVEPATCH support is straight forward.
Add CONFIG_LIVEPATCH_64 and move livepatch stack logic into that item.
Livepatch sample modules all work.
