m68knommu: clean up ColdFire 523x interrupt setup
With the common intc-2 interrupt controller code in place the ColdFire 523x family startup code can be greatly simplified. Remove all the interrupt masking code, and the per-device interrupt config here. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
