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)
