I suspect this might be fixed by ea850f64c272 ("drm/i915/bios: parse DDI ports
also for CHV for HDMI DDC pin and DP AUX channel")

Can you try again with a more recent kernel? Looks like 4.14-rc5 has that, as
does 4.13.8 and 4.9.57. Other stable kernel might have it as well, but I didn't
bother to check that far.

If that doesn't help, then please attach a copy of
/sys/kernel/debug/dri/0/i915_opregion

Oh and since you found something with get-edid on i2c bus 3, can you also check
what /sys/class/i2c-adapter/i2c-3/name says? Pls make sure get-edid is still
reporting the success for bus 3, just in case the bus numbers got shuffled
around.
