During porting support for this router to ath79 target it was discovered that GPIO mapping was incorrect (GPIO11 active high). Correct mapping for both V1 and V2 is GPIO12 active low. Default configuration from GPL source for V2 explicitly states this, and this was confirmed experimentally on ath79 by looking on /sys/kernel/debug/gpio. Correctness of this was also validated for V1 by cross-flashing vendor firmware for V1 on V2 hardware, in which reset button also worked. Fix it.
