    ath79: ZTE MF286[,A,R]: fix WLAN LED mapping
    
    The default configuration of pinctrl for GPIO19 set by U-boot was not a
    GPIO, but an alternate function, which prevented the GPIO hog from
    working. Set GPIO19 into GPIO mode to allow the hog to work, then the
    ath10k LED output can control the state of actual LED properly.
