Subject: [PATCH V2 3/3] USB: serial: option: Add Novatel MiFi 8800L diag endpoint

The Novatel MiFi 8800L can be configured into exposing additional
endpoints by sending four bytes of 0s to the HID endpoint it exposes by
default. One of the additional exposed endpoints is a Qualcomm DIAG protocol
interface. Add the information for that in order to allow it to be used.
