drm/tests: edid: Add edid-decode --check output
Some of our EDIDs are (rightfully) invalid, but most of them should be
valid.
Let's add the edid-decode --check of these EDIDs when they were
generated, so we know what to expect going forward, and a comment to
explicitly mention when we expect them to be broken.
