ARM: dts: exynos: Enable DWC2 dual-role support on OdroidU3+ boards
MicroUSB port on OdroidU3+ boards can operate both as peripheral or as host port. Till now it was configured as pheriperal only port, but it turned out that the DWC2 driver code already handles everything needed to support USB role-switch, so switch it to dual-role (OTG) mode. This has no effect on OdroidU3 (without 'plus') and OdroidX2, which doesn't have USB needed ID pin and VBUS wiring. Those will still operate correctly in pheriperal mode only.
