patch to add product id

Adds new product id to support Sierra Wireless EM7455 modem by u3g kernel
module. Tested on Lenovo Thinkpad T470p. Please note, because of lack of
support QMI protocol by default device is in Low Power Mode, so it need special
nvu-file which sends FCC_AUTH=0 to modem. On Linux it can be done by qmicli
--dms-set-fcc-authentication command.
