[U-Boot] [u-boot 18/40] include: usb: composite: add USB_GADGET_DELAYED_STATUS to avoid compilation error

Added USB_GADGET_DELAYED_STATUS to avoid the following compilation error.
error: ?USB_GADGET_DELAYED_STATUS? undeclared (first use in this function)
while compiling dwc3/ep0.c

While this is been added only to avoid compilation error, the complete fix
should be something like the one added in linux kernel. The complete fix
will be ported once we have the composite driver in u-boot look similar to
the one in linux kernel.
