qmi_wwan/cdc_ether: add device ID for HP lt2523 (Novatel E371) WWAN card

[ Upstream commit 5b9f57516337b523f7466a53939aaaea7b78141b ]

Another rebranded Novatel E371.  qmi_wwan should drive this device, while
cdc_ether should ignore it.  Even though the USB descriptors are plain
CDC-ETHER that USB interface is a QMI interface.  Ref commit 7fdb7846c9ca
("qmi_wwan/cdc_ether: add device IDs for Dell 5804 (Novatel E371) WWAN
card")
