Moving the dw8250_setup_port() call here breaks dw8250_probe_acpi(). It
expects values from the CPR register for the DMA burst size calculation.
The DMA support can be moved to a separate function. This way it can
be called after this point, and it will then be available for both DT
and ACPI. I can make a patch tomorrow. That should solve this issue.
