Thomas Zimmermann 658a933038 drm/ast: Find VBIOS mode from regular display size 
[ Upstream commit c81202906b ]

The ast driver looks up supplied display modes from an internal list of
display modes supported by the VBIOS.

Do not use the crtc_-prefixed display values from struct drm_display_mode
for looking up the VBIOS mode. The fields contain raw values that the
driver programs to hardware. They are affected by display settings like
double-scan or interlace.

Instead use the regular vdisplay and hdisplay fields for lookup. As the
programmed values can now differ from the values used for lookup, set
struct drm_display_mode.crtc_vdisplay and .crtc_hdisplay from the VBIOS
mode.
