    mt7621: fix Belkin RT1800 GPIO
    
    When converting this device to use both GMACs, I mistakenly removed
    state_default, which prevented GPIO LEDs and keys from being used.
    
    Add back and and extra LEDs that were missing.
    
    Tested all LEDs by turning them on.
    
    Fixes: 26a6a6a60ba7 ("ramips: add support for Belkin RT1800")
