Implement the serial break via usb serial. The second data byte in ftdi status packet contains the break status. The values were already defined in usb-serial.c so it was a matter of making use of the event_trigger to form a urb to send over to the host controller with the serial break status set. This was tested against a linux development image which enables sysrq via a serial break on the ftdi usb console. Signed-off-by: Jason Wessel <jason.wessel@windriver.com>
