media: vivid: set min width/height to a value > 0

commit 9729d6d282a6d7ce88e64c9119cecdf79edf4e88 upstream.

The capture DV timings capabilities allowed for a minimum width and
height of 0. So passing a timings struct with 0 values is allowed
and will later cause a division by zero.

Ensure that the width and height must be >= 16 to avoid this.
