[media] vivid-tpg: precalculate downsampled lines
When dealing with vertical downsampling two successive lines have to be
averaged. In the case of the test pattern generator that only happens
if the two lines are using different patterns. So precalculate the average
between two pattern lines: one of pattern P and one of pattern P + 1.
That way there is no need to do any on-the-fly downsampling: it's all done
in the precalculate phase.
This patch also implements horizontal downsampling in the precalculate phase.
The only thing that needs to be done is to half the width since the actual
downsampling happens when two pixels at a time are generated.

[media] DocBook v4l: update bytesperline handling
The documentation says that the bytesperline field in v4l2_pix_format refers
to the largest plane in the case of planar formats (i.e. multiple planes
stores in a single buffer).
For almost all planar formats the first plane is also the largest (or equal)
plane, except for two formats: V4L2_PIX_FMT_NV24/NV42. For this YUV 4:4:4
format the second chroma plane is twice the size of the first luma plane.
Looking at the very few drivers that support this format the bytesperline
value that they report is actually that of the first plane and not that
of the largest plane.
Rather than fixing the drivers it makes more sense to update the documentation
since it is very difficult to use the largest plane for this. You would have
to check what the format is in order to know to which plane bytesperline
belongs, which makes calculations much more difficult.
This patch updates the documentation accordingly.
