    ramips: zbt-wg2626: Add the reset gpio for PCIe port 1
    
    The 2.4GHz interface doesn't come up properly with the log showing:
    
        mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK)
    
    As seen on other MT7621 boards this is caused by a missing reset GPIO.
    The MT7621 dtsi set GPIO 19 as PCIe reset GPIO, which on this board
    reset the 5GHz interface on port 0. Add GPIO 8 to the PCIe reset GPIO
    list to also reset the 2.4GHz interface on port 1.
