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

V3 -> V4: as requested, the patch has been split to 3 sub-patches.
Fix comment format.
V2 -> V3: added this section to tracking changes with previous versions.
Added some explanations about the RSVD(4) in the description session.
Added reservation to port 4 of VID:PID 0x05C6:0x908B to meet other
companies QMI net interface implementation.
V1 -> V2: define UBLOX_PRODUCT_LARA_R6 0x908b has been deleted together
with the previosly provided definition of USB_DEVICE since the PID
is used by another vendor.
The LARA-L6 patch part is the same of the previosly provided one.
