Original change's description:
> [usb][dwc3] Process CommandComplete event on end-transfer
>
> Currently, the core driver contains a 1ms sleep to give time for the
> core to emit a CommandComplete event in response to an EndTransfer
> command signifying DMA has ceased processing. This adds logic to await
> the event and synchronzies the event against other controller operations
> (e.g. reset).
