encoder->type can change underneath us and doesn't need to reflect actual hw state (since we don't construct it from hw state like e.g. encoder->crtc crtc->config). And this can indeed happen: 1) Boot with plugged-in hdmi screen. Since we only set ->type in the probe functions this means we won't detect any infoframes since type is still unkown. 2) First probe sets type to HDMI. 3) If the first modeset now does _not_ happen on the HDMI pipe with infoframes encoder->get_config suddenly sees infoframes and the state checker gets angry. Fix this by only relying on actual hw state when figuring out whether the ddi port is in hdmi mode and sends infoframes.
