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. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
