PPC: Bamboo: fold ppc440.c and ppc440_bamboo.c into a single file

The separation of ppc440 and ppc440_bamboo makes some sense, since ppc440
is the SoC while ppc440_bamboo is the actual board. But the separation
makes things harder for us for no good reason, so let's just fold them
in together with each other.
