m68knommu: make 520x 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 520x UART addressing so that: . UARTs are numbered from 0 up . use a common name for IRQs used Signed-off-by: Greg Ungerer <gerg@uclinux.org>
