Update the documentation of the statsProcessFn() / processLine0() src[]
pointer argument to take into account that swstats_cpu may also be used
with planar input data or with non Bayer single plane input data.

The statsProcessFn typedef is private, so no documentation is generated
for it. Move the new updated src[] pointer argument documentation to
processLine0() so that it gets included in the generated docs.
