    Sierra Wireless EM7565 devices use the QCSERIAL_SWI layout for their
    serial ports

    but need sendsetup = true for the NMEA port to make it work properly.
    
    Simplify the patch compared to v1 as suggested by Bjørn Mork by taking
    advantage of the fact that existing devices work with sendsetup = true
    too.
    
    Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add
    DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID
    0x9090.
    
    Tests with several MC73xx/MC74xx/MC77xx devices have been performed in
    order to verify backward compatibility.
