Update the USB serial option driver support for the Fibocom
FM135-GL
LTE modules as there are actually several different variants.
- VID:PID 2cb7:01a1, FM135-GL are laptop M.2 cards (with
MBIM interfaces for /Linux/Chrome OS)
- VID:PID 2cb7:0115, FM135-GL for laptop debug M.2 cards(with adb
interface for /Linux/Chrome OS)

0x01a1: mbim
0x0115: mbim, diag, at, pipe, adb
