This is wrong if you do this at boot which means you force the same baudrate
on all the console

We must do this only is enable by default of via shell

and some console may not need the setbrg call back (keyboard or fbdev as example)

Also if we want to use a rs232 for controlling a mcu the baud rate may not be the
CONFIG_BAUDRATE

so force it at register is wrong
