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. Before the patch:
root@arm:~# ping -q -f -c 10000 192.168.2.1
PING 192.168.2.1 (192.168.2.1) 56(84) bytes of data.

After the patch:
