Looks like my fault according to git-blame...

I think this happened when making cover-all defconfigs for
multiplatform. I think I just turned everything on... not realizing
that turning on RevB disabled RevA+RevC.

However since it is the *only* version that works with QEMU
it actually makes some kind of weird sense to have it enabled
since the QEMU version is probably more common than
RevA+RevC...
