    image: add FACTORY_SIZE to DEFAULT_DEVICE_VARS
    
    FACTORY_SIZE is used as a device recipe variable on both the D-Link
    DIR-825-B1 and Trendnet TEW-673GRU, but is not listed as a device
    variable, neither globally, nor for ath79. Being assigned the same
    value, this probably hasn't caused any issues.
    
    Add FACTORY_SIZE to the global list DEFAULT_DEVICE_VARS, to ensure the
    variable is reset for every device, and to allow it to be used outside
    of the ath79 target.
