o Add system versions for the P4040(E) and P4080(E).
o In bare_probe(), change the logic that determines the maximum
number of processors/cores into a switch statement and take
advantage of the fact that bit 3 of the SVR value indicates
whether we're running on a security enabled version. Since we
don't care about that here, mask the bit. All -E versions
are taken care of automatically.
