USB: serial: qcserial: add more Lenovo EM74xx device IDs

commit 8d7a10dd323993cc40bd37bce8bc570133b0c396 upstream.

In their infinite wisdom, and never ending quest for end user frustration,
Lenovo has decided to use new USB device IDs for the wwan modules in
their 2017 laptops.  The actual hardware is still the Sierra Wireless
EM7455 or EM7430, depending on region.
