Trying to compile a kerel for ARCH_CO285 fails with the following error:

<--  snip  -->

This does not seem to be a recent breakage.

The ARCH_CO285 support is old - kernel 2.2.0 contains first traces of
it, an it seems to have been pretty complete in later 2.2 kernels.

Since it seems to be completely dead code now this patch therefore
removes it.
