usb: dwc3: Add ENDXFER command polling
ENDXFER polling is available on version 3.10a and later of the
DWC_usb3 (USB 3.0) controller. With this feature, the software can poll
the CMDACT bit in the DEPCMD register after issuing an ENDXFER command.
This feature is enabled by writing GUCTL2[14].
This feature is NOT available on the DWC_usb31 (USB 3.1) IP.
