[igt-dev] [PATCH i-g-t v4 14/14] igt: tests: chamelium: Add YUV formats tests

[Maxime Ripard]

The NV12, NV16, NV21, NV61, YUV420, YVU420, YUV422 and YVU422 are YUV
formats that are currently supported in IGT.

We'll want to test those formats in addition to the RGB formats, so
let's add some subtests. One thing worth noting is some hardware isn't
able to output a pixel-perfect image, so we do the same kind of
comparison than for VGA.
