According to bspec, we need to subtract an additional line from vtotal for interlaced modes and vblank_end needs to equal vtotal. All other timing fields do not need this special treatment, so kill it.
Bspec says that this is irrespective of whether the interlaced mode has an odd or even vtotal, both modes are supported.
