Hi,

There are many evaluationboard that use mini-usb port like as a serial 
port + power supply.
Using it as serial console have to force getty with no need for carrier 
detect.
For these boards have to use USB_SERIAL_CONSOLE variabile in config file 
instead of SERIAL_CONSOLE and getty runs with -L parameter.
By this way is simple to use usb serial port unless know in depth getty 
manpage.

Can you merge this patch in mainline?
