m68knommu: move ColdFire INTC definitions to new include file
Create an mcfintc.h include file with the definitions for the old style ColdFire interrupt controller. They are only needed on CPU's that use this old controller - so isolate them on their own. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
