m68knommu: simplify ColdFire "timers" clock initialization

The ColdFire "timers" clock setup can be simplified. There is really no
need for the flexible per-platform setup code. The clock interrupt can be
hard defined per CPU platform (in CPU include files). This makes the
actual timer code simpler.
