[igt-dev] [PATCH i-g-t v3 20/21] chamelium: Move the YUV tests over to the checkerboard checking method

[Paul Kocialkowski]

Now that the checkerboard frame checking method is available through
the frame match helper, make use of it in YUV tests to increase the
reliability of the results.

The analog test tends to provide false positives, which are properly
detected by the checkerboard method in most instances.
