m68k: mcfmmu: remove stale part of comment about steal_context

The comment about steal_context() came from powerpc and a part of it
addresses differences between powerpc variants that are not really
relevant to m68k.

Remove that part of the comment.

/*
* Steal a context from a task that has one at the moment.
* This is only used on 8xx and 4xx and we presently assume that
* they don't do SMP. If they do then thicfpgalloc.hs will have to check
* whether the MM we steal is in use.
* We also assume that this is only used on systems that don't
* use an MMU hash table - this is true for 8xx and 4xx.
* This isn't an LRU system, it just frees up each context in
* turn (sort-of pseudo-random replacement :). This would be the
* place to implement an LRU scheme if anyone was motivated to do it.
