Kernels built for e500 and e500mc are fundamentally incompatible with
each other due to different cacheline sizes, support for SPE
instructions, etc.
Unfortuantely, there is a lot of support code with a morass of config
options which mostly mean the same things (E500/E500MC/PPC_85xx/etc).
As preparation for fixing up all the support code, split the config
options into two separate parts.
