base-modem: allow looking for the QMI port associated to a given data port

Browse Source 
QMI and wwan ports come in pairs. Each wwan port has an associated control QMI
port, which is the only port allowed to send the Start|Stop Network QMI requests
to start|stop the connection in the given wwan interface.

Paired QMI and wwan interfaces (should) share the same parent udev device,
quoting Bjørn:

    "If we ignore the unfortunate 3.4 and 3.5 kernels, then a matching wwanX
     and cdc-wdmY set will always share the same parent USB interface on QMI
     devices.

     Having the same parent USB device is *not* sufficient.  You cannot control
     wwan0 using cdc-wdm1 in the above example."
