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. Signed-off-by: Alexander Graf <agraf@suse.de>
