[ Upstream commit 17763960b1784578e8fe915304b330922f646209 ]
When setting the EDID it would attempt to update two controls
that are only present if there is an HDMI output configured.
If there isn't any (e.g. when the vivid module is loaded with
node_types=1), then calling VIDIOC_S_EDID would crash.
Fix this by first checking if outputs are present.

In several places a division by fmt->vdownsampling[p] was
missing in the sizeimage[p] calculation, causing incorrect
behavior for multiplanar formats were some planes are smaller
than the first plane.
Found by new v4l2-compliance tests.
