Can't really test this display without this patch and I do not have other
HDMI/DVI screens. And this issue does not happen with other HDMI displays
that I have here.

Yes. Without those patches display is not detected by u-boot (issues with
missing hpd pin and stricter edid checks), so kernel initializes display.

Disabling those patches is mostly the same as disabling the HDMI support
in u-boot the kernel side.

Xorg logs for scenario 1 and 2 are basically the same whether or not
HDMI is enabled in u-boot. Now, differences arise when DDC clock is
marked as critical. Attached files:
* Xorg.0.ddc-critical.log
* Xorg.0.ddc-default.log

Also attached drm.debug outputs.
