m68knommu: make 528x UART platform addressing consistent
If we make all UART addressing consistent across all ColdFire family members
then we will be able to remove the duplicated plaform data and use a single
setup for all.
So modify the ColdFire 528x UART addressing so that:
. UARTs are numbered from 0 up
. use a common name for IRQs used
