usb: udc: Fix gadget driver's speed check in various UDC drivers
Several UDC drivers had a gadget driver's speed sanity check of the form of: driver->speed != USB_SPEED_HIGH or: driver->speed != USB_SPEED_HIGH && driver->speed != USB_SPEED_FULL As more and more gadget drivers support USB SuperSpeed, driver->speed may be set to USB_SPEED_SUPER and UDC driver should handle such gadget correctly. The above checks however fail to recognise USB_SPEED_SUPER as a valid speed. This commit changes the two checks to: driver->speed < USB_SPEED_HIGH or: driver->speed < USB_SPEED_FULL respectively.
