USB: dwc3_otg: Set peripheral mode before re-initializing core
Moving from host to peripheral mode requires performing hardware
reset and re-initializing core. DWC3 core mode must be changed to
peripheral before DEVICE specific initialization, otherwise,
EP0 initialization would fail due to mode set to HOST and USB
wouldn't enumerate in peripheral mode.
