USB: Add simple serial subclass support
This uses the newly allocated simple serial SubClass
and Protocol identifiers to make enumeration of serial
consoles over USB easier. The simple usb serial kernel
driver can select based on vid/class/subclass/protocol,
making it trivial to attach to serial consoles.

Enable USB console on discovery-stm32f072 and verify
that a new ttyUSB? device is discovered.
