m68knommu: fix coldfire tcdrain
Fix tcdrain on coldfire uarts.
Currently with coldfire uarts tcdrain returns without waiting for txempty,
because (tx)fifosize is 0. Fix that and call uart_update_timeout when
setting the baud rate, otherwise tcdrain will wait for an half our :)
Also constify mcf_uart_ops.
