Add the USB device ID for the Compal EXM-G1x modem. Bind its QMI WWAN interface 8 and expose its vendor-specific serial interfaces with protocols 0x30, 0x40, and 0x60 through the option driver. Tested on a Compal EXM-G1x modem.
Do you know which chipset this is based on?

Please split this in two patches as this will go in through two different subsystems. Please also include the output of usb-devices (or lsusb -v) in the commit message (at least for usb serial).
