m68knommu: map ColdFire interrupts to correct masking bits
The older simple ColdFire interrupt controller has no one-to-one mapping of interrupt numbers to bits in the interrupt mask register. Create a mapping array that each ColdFire CPU type can populate with its available interrupts and the bits that each use in the interrupt mask register. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
