Defeature Display Interlace support. Support for interlace modes is removed from Gen 12 onwards. Pruning the interlace modes for HDMI for Display >=12. Bspec: 50490 v2: Add check for both DP and HDMI. (Ville) Get rid of redundant check for interlace mode in modevalid. (Ville) v3: Simplify the condition to avoid interlace modes.
