V4L/DVB: uvcvideo: Restrict frame rates for Chicony CNF7129 webcam
At all frame rates except 30fps and 5fps the camera produces very dark
pictures. Auto-exposure is probably disabled by the camera at all frame
rates except 30fps, making them pretty unusable.
Work around the problem by introducing a new RESTRICT_FRAME_RATE quirk
that disables all the frame rates except the default one.
