m68knommu: simplify the 5206 UART setup code
Browse files Browse the repository at this point in the history
Simplify the UART setup code so that it no longer loops for each UART
present. Just make it do all the work it needs in a single function.
This will make the code easier to share when we move to a single set
of platform data for ColdFire UARTs.
