usb: gadget: webcam: fix V4L2 Kconfig dependency
Configuring the USB_G_WEBCAM driver as built-in leads to a link error when CONFIG_VIDEO_V4L2 is a loadable module: drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_setup': f_uvc.c:(.text+0xfe): undefined reference to `v4l2_event_queue' drivers/usb/gadget/function/f_uvc.o: In function `uvc_function_ep0_complete': f_uvc.c:(.text+0x188): undefined reference to `v4l2_event_queue' This changes the Kconfig dependency to disallow that configuration, and force it to be a module in that case as well. This is apparently a rather old bug, but very hard to trigger even in thousands of randconfig builds.
