A recent patch introduced support for superspeed plus (USB3.1), but that caused a new gcc warning in the XHCI code:
usb/host/xhci.c: In function 'xhci_drop_ep_from_interval_table': usb/host/xhci.c:2440:2: error: enumeration value 'USB_SPEED_SUPER_PLUS' not handled in switch [-Werror=switch]
This changes the XHCI driver to handle USB_SPEED_SUPER_PLUS the same way as USB_SPEED_SUPER in the xhci_drop_ep_from_interval_table and xhci_add_ep_to_interval_table functions, explicitly ignoring it.
