[PATCH] docs/about: Deprecate the 'next-cube' m68k machine

[Thomas Huth]

The machine is incomplete, and unfortunately the hoped-for improvements
never happened. So it's maybe best if we mark this machine as deprecated
and finally remove it again in case it gets into the way of a code
refactoring or other reasons.
