Try to make the display VT-d workarounds more robust.

Ville Syrjälä (5):
  drm/i915: Move VT-d alignment into plane->min_alignment()
  drm/i915: Use more optimal VTd alignment for planes
  drm/i915: Calculate the VT-d guard size in the display code
  drm/i915: Use per-plane VT-d guard numbers
  drm/i915/fbdev: Use fb->normal_view.gtt
