Add a binding document for a generic serdev-ngsm driver that can be used to bring up TS 27.010 line discipline with Linux n_gsm support on a serial port. As the Motorola Mapphone modems require some custom handling, they are handled with a separate compatible. Let's also add vendor string for ETSI as we're using a ETSI 3GPP TS 27.010 standard.
