powerpc/ftrace: Activate HAVE_DYNAMIC_FTRACE_WITH_REGS on PPC32
Unlike PPC64, PPC32 doesn't require any special compiler option
to get _mcount() call not clobbering registers.
Provide ftrace_regs_caller() and ftrace_regs_call() and activate
HAVE_DYNAMIC_FTRACE_WITH_REGS.
That's heavily copied from ftrace_64_mprofile.S
For the time being leave livepatching aside, it will come with
following patch.
