ath79: ZTE MF286[A,R]: add "Power button blocker" GPIO switch
ZTE MF286A and MF286R feature a "power switch override" GPIO in stock firmware as means to prevent power interruption during firmware update, especially when used with internal battery. To ensure that this GPIO is properly driven as in stock firmware, configure it with userspace GPIO switch. It was observed that on some units, the modem would not be restarted together with the board itself on reboot, this should help with that as well.
