ARM: dts: imx6qdl-wandboard: Add usbotg support

Tested via g_ether:

$ modprobe g_ether
using random self ethernet address
using random host ethernet address
usb0: HOST MAC 42:b5:26:a9:48:21
usb0: MAC 36:a6:85:9b:9e:13
using random self ethernet address
using random host ethernet address
g_ether gadget: Ethernet Gadget, version: Memorial Day 2008
g_ether gadget: g_ether ready
$ g_ether gadget: high-speed config #1: CDC Ethernet (ECM)
$ ifconfig usb0 10.0.0.2

Then on the PC host side:

~$ sudo ifconfig usb0 10.0.0.1
~$ ping 10.0.0.2
