uvc-gadget.sh: add function to create frame size
Currently there are a set of files that need to be written to in configfs to instantiate a single frame size of a UVC function. Add a function create_frame() to do this in one call. There is no delete_frame() since delete_uvc() will delete the frame settings. Previously delete_uvc() only deleted the single frame size, so this has been changed to a wildcard to catch all frame sizes.
