    ramips: overwrite reset gpio properties in EX6150 DTS
    
    The Netgear EX6150 can, just like the D-Link DIR-860L rev B1, fail to
    initialise both radios in some cases. Add the reset GPIOs explicitly
    so the PCI-E devices get re-initialised properly. See also FS #3632.
    
    Error shows up in dmesg as follows:
    
      [    1.560764] mt7621-pci 1e140000.pcie: pcie1 no card, disable it (RST & CLK)
