ARM: dts: imx6qdl-dhcom: Add USB overcurrent pin on SoM layer

Browse Source 
Add USB overcurrent pin muxing on SoM layer. On DRC02 and PDK2 the USB
overcurrent pin isn't connected, but a USB hub on the board takes care
of the USB overcurrent instead. Therefore disable it there with the
property disable-over-current.
