From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
The core doesn't flag scaling_filter prop changes as needing
a modeset. That doesn't work for us since we only reprogram the
pipe scaler during full modesets and fastsets. So we need to
flag the prop change as a modeset ourselves. Assuming nothing else
has changed the operation will get promoted (demoted?) to a fastset
later.
