dz: clean up and improve the setup of termios settings
A set of changes to the way termios settings are propagated to the serial port hardware. The DZ11 only supports a selection of fixed baud settings, so some requests may not be fulfilled. Keep the old setting in such a case and failing that resort to 9600bps. Also add a missing update of the transmit timeout. And remove the explicit encoding of the line selected from writes to the Line Parameters Register as it has been preencoded by the ->set_termios() call already. Finally, remove a duplicate macro for the Receiver Enable bit. Signed-off-by: Maciej W.
