Add a device match entry for Telit Cinterion LE310X1 RNDIS interface
(VID:PID 1bc7:7030).
This is a functional no-op and keeps using the generic rndis_info for now.
Power-management behavior is handled in a follow-up patch.

Enable autosuspend support for Telit Cinterion LE310X1 RNDIS interface
by selecting a driver_info variant with manage_power callback.
This keeps power management scoped to the new Telit ID only, and avoids
changing behavior for all existing RNDIS devices.
