Move common ColdFire CPU vectors.c to common coldfire platform directory. Currently the common ColdFire CPU family code sits in the arch/m68knommu/platform/5307 directory. This is confusing, the files containing this common code are in no way specific to the 5307 ColdFire. Create an arch/m68knommu/platform/coldfire directory to contain this common code. Other m68knommu CPU varients do not need use this code though, so it doesn't make sense to move it to arch/m68knommu/kernel.
