ARM: dts: imx6qdl-wandboard: use GPIO_6 for FEC interrupt
Apply the same work-around for i.MX 6D/Q erratum 006687 as used for Sabre Lite for the Wandboard Dual / Quad. Like on the Sabre Lite, GPIO6 is used as a power down output for camera expansion boards. However, these expansion boards do not work with mainline yet anyway. Tested on a Wandboard Quad.
