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.

 * Most of the older ColdFire parts use the same simple interrupt

 * controller. This is currently used on the 5206, 5206e, 5249, 5307

 * and 5407 parts.

 *

 * The builtin peripherals are masked through dedicated bits in the

 * Interrupt Mask register (IMR) - and this is not indexed (or in any way

 * related to) the actual interrupt number they use. So knowing the IRQ

 * number doesn't explicitly map to a certain internal device for

 * interrupt control purposes.
