This patch merges support for all DB1xxx and PB1xxx
boards into a single image.

So far I've only tested it on a DB1500 and DB1300, as these are all I
have access to right now. I've also removed Big-Endian support for now
I've received a report that BCSR handling isn't big-endian safe, but
fixing it for all devboards turned out to be quite a challenge...
