qmi_wwan/cdc_ether: move Novatel 551 and E362 to qmi_wwan
These devices provide QMI and ethernet functionality via a standard CDC ethernet descriptor. But when driven by cdc_ether, the QMI functionality is unavailable because only cdc_ether can claim the USB interface. Thus blacklist the devices in cdc_ether and add their IDs to qmi_wwan, which enables both QMI and ethernet simultaneously.
