m68knommu: merge old ColdFire interrupt controller masking macros
Currently the code that supports setting the old style ColdFire interrupt
controller mask registers is macros in the include files of each of the
CPU types. Merge all these into a set of real masking functions in the
old Coldfire interrupt controller code proper. All the macros are basically
the same (excepting a register size difference on really early parts).
