musb udc code depends on usb gadget code provided by CONFIG_USB_DEVICE and defined in drivers/usb/gadget/Makefile. But this Makefile is not included into U-Boot build when CONFIG_USB_GADGET is not set. As CONFIG_USB_DEVICE cannot be enabled together with CONFIG_USB_GADGET it means that dependency for musb udc code is not compiled during build. Fix it by including drivers/usb/gadget dependency also when CONFIG_USB_DEVICE is set.
This patch fixes compile errors:
