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.
