Subject: 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.
