The ColdFire 54xx family shares the same interrupt controller used on the 523x, 527x and 528x ColdFire parts, but it isn't offset relative to the IPSBAR register. The 54xx doesn't have an IPSBAR register. By including the base address of the peripheral registers in the register definitions (MCFICM_INTC0 and MCFICM_INTC1 in this case) we can avoid having to define a fake IPSBAR for the 54xx. And this makes the register address definitions of these more consistent, the majority of the other register address defines include the peripheral base address already.
