Nautiyal, Ankit K Oct. 17, 2022, 2:30 p.m. UTC
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)
