I don't think removing TEST_ONLY is correct? bafd90661c26 ("tests/kms_hdr: =
Add
bpc switch subtests") reads:

    v4: -Plane size back to CRTC size, regression observed in hsw again
         "Plane must cover entire CRTC" because of plane size restriction
         to 512x512. Petri/Ville suggested to use TEST_ONLY in try_commit()
         to probe whether we can use a smaller than fullscreen plane.
