    ath79: ZTE MF286[,A,R]: use GPIO19 as ath9k LED
    
    With the pinctrl configuration set properly by the previous commit, the
    LED stays lit regardless of status of 2.4GHz radio, even if 5GHz radio
    is disabled. Map GPIO19 as LED for ath9k, this way the LED will show
    activity for both bands, as it is bound by logical AND with output of
    ath10k-phy0 LED. This works well because during management traffic,
    phy*tpt triggers typically cause LEDs to blink in unison.
