I don't think bisecting is useful, it'll most likely just identify
commit 040dda2e1f52 ("drm/amd/display: Error print when ATOM BIOS
implementation is missing") which started printing these messages for
missing ATOM BIOS implementations.

I'm not sure, but I suspect these messages are harmless, given that
things are otherwise presumably still working as well as they were before.
