Subject: [PATCH -next] usb: fotg210: Fix build error when CONFIG_USB_FOTG210_UDC=y && CONFIG_USB_GADGET=m

The combination of CONFIG_USB_FOTG210_UDC=y and
CONFIG_USB_GADGET=m results in the following error:

drivers/usb/fotg210/fotg210-udc.o: In function `fotg210_done':

make[1]: *** [vmlinux] Error 1

Make USB_FOTG210_UDC depends on USB_GADGET=y to fix this.
