m68knommu: make ColdFire SoC selection a choice

commit fa95a1dd upstream.

It would be nice if we could support multiple ColdFire SoC types in a
single binary - but currently the code simply does not support it.
Change the SoC selection config options to be a choice instead of
individual selectable entries.

This fixes problems with building allnoconfig, and means that a sane
linux kernel is generated for a single ColdFire SoC type.
