m68knommu: external interrupt support to ColdFire intc-2 controller
The EDGE Port module of some ColdFire parts using the intc-2 interrupt controller provides support for 7 external interrupts. These interrupts go off-chip (that is they are not for internal peripherals). They need some special handling and have some extra setup registers. Add code to support them. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
