The console_tbl has enough support functions to handle any type of
UART.  Some make a distinction between control and data registers.
Some don't.  THose that do not, ignore those fields.

I think the real HW driver will have to be intercept this and act upon
it as part of the ioctl() processing.  I think it might require an addition
to the  rtems_termios_callback OR (nicer) a new interpretation of some
piece of data in struct termios so setAttributes can work.
