m68knommu: remove use of MBAR in old-style ColdFire timer

Browse source 
Not all ColdFire CPUs that use the old style timer hardware module use
an MBAR set peripheral region. Move the TIMER base address defines to the
per-CPU header files where we can set it correctly based on how the
peripherals are mapped - instead of using a fake MBAR for some platforms.
