From: Clint Taylor <clinton.a.tay...@intel.com>
Intel HDMI does not correctly configure pixel replicated HDMI modes
480i and 576i. Remove support for these modes until DRM has been
changed to correctly identify SD interlaced modes by reporting there
true horizontal resolution 720 instead of the pre-pixel doubled 1440.
