usb: dwc3: Add support for gsi endpoint disable operation
gsi driver does not call the gadget API usb_ep_enable()
instead uses gsi ep operation call back to enable gsi ep.
As a result ep->enabled flag remains clear. Later function
driver calls usb_ep_disble() API from gadget framework and
ep disable operation gets skipped. Fix this by adding gsi ep
operation for ep disable. This makes the enable and
disable ep operations both handled by gsi ep ops.
