Note that CONFIG_PPC_OF is always set in arch/powerpc since that
includes support for the flat device-tree... We might want to keep a
separate option for prom_init.c, though I'm not too big about it right
now. Maybe CONFIG_PPC_BOOT_FROM_OF :) That would allow custom kernel to
be shrunk down if they don't need to support platforms that are known
not to have a real OF (iSeries for example).
