[PATCH gnumach] console: Fix baud rate on com ports, use 115200 default baud, 8 data bits

[Damien Zammit]

TESTED: By booting gnumach off an HP T620 with console=com0 and receiving 
115200 8N1 console
on another machine connected via the serial port in minicom.
Without this patch, part of the console is garbled by mismatching com params 
(9600 7N1).
