[PATCH] m68knommu: modify the ColdFire PIT timer for new 5208

Modified common ColdFire PIT timer code to support the 5208 as well.
It uses a different set of mask and interrupt bits than other ColdFire
processors. The defines for these bits have been moved in header
files and set appropriately for the different processor varients.
Patch originally from Matt Waddel.
