This patch does a few cleanups of arch/ppc64/kernel/prom_init.c, making
the RTAS instanciation code more readable & more robust, fixing a bug
in the code bringing in additional CPUs (would work with IBM firmware,
but not with another firmware of an upcoming platform), plus remove some
old commented out cruft left-over from the big cleanup.
