[PATCH v2] usb: dwc3: gadget: wait for End Transfer to complete

Instead of just delaying for 100us, we should actually wait for End Transfer Command Complete interrupt before moving on. Note that this should only be done if we're dealing with one of the core revisions that actually require the interrupt before moving on. [ felipe.ba...@linux.intel.com: minor
