Anthony Koo abe882a39a drm/amd/display: fix issue with eDP not detected on driver load ... [Why] HPD not going to be high if Panel VDD is off And all AUX transaction will fail :( [How] 1. Power on VDD before attempting detection if it isn't already on 2. Improve the robustness by having a retry mechanism on the first DPCD read after VDD on. If a particular board always holds HPD high incorrectly, the AUX access may fail, so we can retry in those scenarios. This change would only improve logic since it prevents AUX failure leading to bad resolution on internal panel. 3. We should never need to re-detect internal panel, so logic is re-arranged a bit to skip earlier.
