I think I'm going to go with a single defconfig for all 5200 boards
for the time being.  We can revisit later if it turns out not to be
working.  Here are my reasons:

- mpc5200 is intended to be multiplatform.  Using a common defconfig
increases the likelyhood that a kernel with support for all 5200
platforms will actually get tested.
- Reduces the time cost required to build all powerpc defconfigs (only
1 needed instead of 5 and growing)
- defconfigs are intended to be the known working configuration; not
necessarily an optimized for deployment configuration.  The
system/kernel engineer is still responsible to tailor the
configuration for a shippable distribution.
