USB: serial: option: add u-blox LARA-R6 00B modem

commit d9e37a5c4d80ea25a7171ab8557a449115554e76 upstream.

The official LARA-R6 (00B) modem uses 0x908b PID. LARA-R6 00B does not
implement a QMI interface on port 4, the reservation (RSVD(4)) has been
added to meet other companies that implement QMI on that interface.

LARA-R6 00B USB composition exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions
