m68knommu: make ColdFire IMR and IPR register definitions absolute addresses
Make all definitions of the ColdFire Interrupt Mask and Pending registers
absolute addresses. Currently some are relative to the MBAR peripheral region.
The various ColdFire parts use different methods to address the internal
registers, some are absolute, some are relative to peripheral regions
which can be mapped at different address ranges (such as the MBAR and IPSBAR
registers). We don't want to deal with this in the code when we are
accessing these registers, so make all register definitions the absolute
address - factoring out whether it is an offset into a peripheral region.
This makes them all consistently defined, and reduces the occasional bugs
caused by inconsistent definition of the register addresses.
