Pixel replicated modes should be 720 horizontal pixel and pixel replicated by the HW across the HDMI cable at 2X pixel clock. Current horizontal resolution of 1440 does not allow pixel duplication to occur and scaling artifacts occur on the TV. HDMI certification 7-26 currently fails for all pixel replicated modes. This change fizes the HDMI certification issues with 480i/576i.
V2: Removed interlace flag from VICs 44 and 45. Will be submitted in another patch. Various other formatting fixes.

I think the i915 side of this double-clock support should be split out into a separate patch. Makes it easier for people to spot that there's some driver work to enable this properly. -Daniel
