Indeed on ICL we only see:
DEBUG: i2c edids:1 drm edids:2 vga outputs:0  

Also the bug has not been seen on ICL in 3 weeks (since CI_DRM_6085). Prior to
that reproduction rate was ~ 1 every 5 CI_DRMs. We are now at CI_DRM_6225,
which is more than 5x10=50 runs since last occurence, taking ICL tag out.


On everything else we have some occurrences happening the other way aroudn:
(i915_pm_rpm:1086) DEBUG: i2c edids:1 drm edids:0 vga outputs:0

The patches made by Oleg will allow us to get more details on this by tying the
i2c devices to connectors on the kernel side, and then the test logging more
information about the failure - which connector, what part has failed (readout?
do we have a mismatch?) and dump the raw values.

Keeping the bug high, as not having you monitor EDID read out correctly by DRM
is a serious problem for users.
