Add ids for Qualcomm Gobi 2000 QDL and Modem modes. Gobi 2000 has a single altsetting in QDL mode, so adapt code to handle that. Firmware upload protocol is also slightly different, with an additional firmware file. However, qcserial doesn't handle firmware uploading. Tested on Lenovo Thinkpad T510.
