This causes modeset to pick mode with wrong aspect ratio, eventually cauing failures in HDMI compliance test cases, due to wrong VIC. This patch adds aspect ratio information in DRM's mode conversion and mode comparision functions, to make sure kernel picks mode with right aspect ratio (as per the VIC).
