rndis_host: enable power management for Telit LE310X1

Browse Source 
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.
