m68knommu: remove ColdFire CLOCK_DIV config option
The reality is that you do not need the abiltity to configure the clock divider for ColdFire CPUs. It is a fixed ratio on any given ColdFire family member. It is not the same for all ColdFire parts, but it is always the same in a model range. So hard define the divider for each supported ColdFire CPU type and remove the Kconfig option.
