This series improves the uvc video gadget by parsing the configfs
entries. With the configfs data, the driver now is able to negotiate the
format with the usb host in the kernel and also exports the supported
frames/formats/intervals via the v4l2 VIDIOC interface.

usb: gadget: uvc: move structs to common header
usb: gadget: uvc: add VIDIOC function
usb: gadget: uvc: add format/frame handling code
