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.

Two patches will work. The HDMI driver will just reject the SD
interlaced modes without the i915 changes.
