Add VID/PID 33f8:1003 for the Rolling Wireless RW135R-GL M.2 module,
which is used in laptop debug cards with MBIM interface for
Linux/Chrome OS. The device supports mbim, pipe functionalities.

Here are the outputs of usb-devices:

Changes in v4:
- Remove unnecessary .driver_info = RSVD(5)
- Fix subject format: use git format-patch -v4 to generate clean versioned subject
- Finalize commit message: keep only core MBIM functionality description
