USB: serial: option: add LARA-R6 01B PIDs

The new LARA-R6 product variant identified by the "01B" string can be
configured (by AT interface) in three different USB modes:

* Default mode (Vendor ID: 0x1546 Product ID: 0x1311) with 4 serial
interfaces

* RmNet mode (Vendor ID: 0x1546 Product ID: 0x1312) with 4 serial
interfaces and 1 RmNet virtual network interface

* CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1313) with 4 serial
interface and 1 CDC-ECM virtual network interface
The first 4 interfaces of all the 3 USB configurations (default, RmNet,
CDC-ECM) are the same.

In default mode LARA-R6 01B exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions

In RmNet mode LARA-R6 01B exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions
If 4: RMNET interface

In CDC-ECM mode LARA-R6 01B exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions
If 4: CDC-ECM interface
