    lantiq: xway: add phy reset pin to AVM Fritz!Box 7320
    
    This commit adds the PHY reset gpio for the LAN1 port to the dts.
    According to the GPL sources, gpios 34 and 36 are used on the AVM
    FritzBox 7320 and 7330. The second port is unsupported.
    
    The gpio assignment has been verified on the FritzBox 7330.
