From: Greg Ungerer <gerg@xxxxxxxxxxx>
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
