The v4l2-compliance tool expects that if VIDIOC_CROPCAP is defined, then VIDIOC_G_SELECTION for TGT_CROP_BOUNDS/DEFAULT is also defined (or COMPOSE in the case of an output device). In fact, all that a driver has to do to implement cropcap is to support those two targets since the v4l2 core will implement cropcap and fill in the pixelaspect to 1/1 by default. Implementing cropcap is only needed if the pixelaspect isn't square. So implement g_selection instead of cropcap in uvc to fix the v4l2-compliance failure.
