cdc_ether: add usb id for Ericsson F3507g

commit cac477e8f1038c41b6f29d3161ce351462ef3df7 upstream.

The Ericsson F3507g wireless broadband module provides a CDC Ethernet
compliant interface, but identifies it as a "Mobile Direct Line" CDC
subclass, thereby preventing the CDC Ethernet class driver from picking
it up.  This patch adds the device id to cdc_ether.c as a workaround.

Ericsson has provided a "class" driver for this device:

But closer inspection of that driver reveals that it adds little more
than duplication of code from cdc_ether.c.  See also
