m68knommu: general interrupt controller for ColdFire 532x parts
The ColdFire 532x family of parts uses 2 of the same INTC interrupt controlers used in the ColdFire 520x family. So modify the code to support both parts. The extra code for the second INTC controler in the case of the 520x is easily optimized away to nothing. Signed-off-by: Greg Ungerer <gerg@uclinux.org>
