USB: tty: SprogII DCC controller identifiers

Someone on rmweb reminded me this had been overlooked from ages ago..

Add the identifiers for the Sprog II USB. This is a DCC control interface
using the FTDI-SIO hardware: http://www.sprog-dcc.co.uk/. People have been
using it with insmod options for ages, this just puts it into the driver
data.
