From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Check the mode flags from the adjusted_mode, not user requested mode.
The hdisplay/vdisplay check actually checkes the primary plane size,
so those still need to come from the user requested mode.
Extract both modes from pipe config instead of the drm_crtc.
