powerpc: Delete old PrPMC 280/2800 support
This processor/memory module was mostly used on ATCA blades and before that, on cPCI blades. It wasn't really user friendly, with custom non u-boot bootloaders (powerboot/motload) and no real way to recover corrupted boot flash (which was a common problem). As such, it had its day back before the big ppc --> powerpc move to device trees, and that was largely through commercial BSPs that started to dry up around 2007. Systems using one were largely in a "deploy and sustain" mode, so interest in upgrading to new kernels in the field was nil. Also, requiring 50A, 48V power supplies and a 2'x2'x2' ATCA chassis largely rules out any hobbyist/enthusiast interest. The point of all this, is that we might as well delete the in kernel files relating to this platform. No point in continuing to build it via walking the defconfigs or via linux-next testing.
