    Many PCMCIA GPRS modems like: Onda Edge N100E, Novaway PC98 (OEM SPC98Z),
    Rovermate Edgus Adaptmate-039 and others have same construction and
    identification:
    
    lspcmcia -vvv
    Product Name:   Generic Modem: MD55x 1.00 Serial number: xxxxx-xxx
    Identification: manf_id: 0x015d card_id: 0x4c45
                    function: 2 (serial)
                    prod_id(1): "Generic" (0xc49e4731)
                    prod_id(2): "Modem: MD55x" (0x8913b110)
                    prod_id(3): "1.00" (0x83dbf271)
                    prod_id(4): "Serial number: xxxxx-xxx" (0x73ee9514)
    
    Serial connection to GSM module based on Elan VPU16551 PCMCIA UART with
    datasheet recommeded 14.7456MHz crystal oscillator.
    
    By default serial_cs set UART clock == 1843200 Hz
    For correct work need set clock 14745600 Hz.
    This quirk already present in driver, only need add device in quirk list.
