uart: use an unsigned int for baud rate rather than speed_t
...
uart.c contains a static conversion function that will translate known
baud rates into their speed_t counter parts. If an unsupported baud
rate is selected, a diagnostic will be emitted via syslog and a
default of B9600 will be chosen.
