7436a87db9 drm/tests: hdmi: check the infoframes behaviour 
Verify the InfoFrames behaviour. Check that reporting InfoFrame as
unsupported doesn't result in a commit error. Also check that HDR and
Audio InfoFrames are not triggered if corresponding features are not
enabled.

d618363a53 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.

b17ade59aa drm/tests: edid: Update CTA-861 HDMI Vendor Specific Data Block 
For some reason, the HDMI VSDBs in our kunit EDIDs had a length longer
than expected.

While this was harmless, we should get rid of it to make it somewhat
predictable.

2bf85c45db drm/tests: edid: Fix monitor range limits 
For some reason, some EDIDs used by kunit had Monitor Range Limits
making no sense, and not matching the edid-decode output in the comment.

While they were in the comments as:
    Display Range Limits:
      Monitor ranges (GTF): 50-70 Hz V, 30-70 kHz H, max dotclock 150 MHz

They were actually:
    Display Range Limits:
      Monitor ranges (GTF): 50-70 Hz V, 0-0 kHz H, max dotclock 1960 MHz

Fix that section of the EDIDs to match the expected edid-decode output.

945f516ed3 drm/tests: Add HDMI connector bpc and format tests 
The previous patch added the bpc and format an HDMI connector needs to
be set up with for a given connector state.

Let's add a few tests to make sure it works as expected.
