[PATCH 05/23] m68knommu: make 5272 UART platform addressing consistent

[<gerg@xxxxxxxxxxxx>]

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 5272 UART addressing so that:

. UARTs are numbered from 0 up
. base addresses are absolute (not relative to MBAR peripheral register)
