    lantiq: xrx200: convert FritzBox 7360v2's wifi to nvmem
    
    this was thoroughly tested (warm and cold boots). on a
    real 7360v2. This is because there have been documented
    hick-ups with other lantiq devices that need the
    owl-loader too.
    
    It's likely that the 7360(sl) could be converted in the
    same way as well. However the 7362sl uses a reversed
    caldata format, so the "qca,no-eeprom" stays in place.
    
    The patch also moves the urloader nvmem partition
    definition into the partition section.
