Have the port use GMAC1 with internal switch
which fixes the issue of the ethernet LED not functioning
The LED is triggered by the internal switch, not a GPIO.
The GPIO for the ethernet LED was added in ath79
as it was defined in the ar71xx target
but it was not functioning in ath79 for a previously unknown reason.
It is unknown why that GPIO was defined as an LED in ar71xx.
