    ath79: fix/improve LED control for TL-WPA8630 v1/v2
    
    The TL-WPA8630 v1 and v2 have the same LED Control GPIO configuration
    according to the TP-Link GPL sources. Set the GPIO to output to make
    it work and set to Active Low. It defaults to LEDs on at bootup.
    
    To turn all LEDs off:
      echo 0 > /sys/class/gpio/tp-link\:led\:control/value
    To turn all LEDs on:
      echo 1 > /sys/class/gpio/tp-link\:led\:control/value
    
    Change the "LED" button from BTN_0 to KEY_LIGHTS_TOGGLE to match other
    devices and the button guide, and to reduce the number of unintuitive
    "BTN_X" inputs.
