[PATCH] m68knommu: add 5208 ColdFire pit interrupt support 

The PIT timer in the 5208 ColdFire has slightly different interrupt
bit definitions than the PIT timer used on other ColdFire parts.
Define the commonly used bit and mask numbers here, and let
part specific defines take precedence if they are defined.

Patch originally from Matt Wadell (from code originally written by
Mike Lavender).
