drm/i915: Move VT-d alignment into plane->min_alignment()
Currently we don't account for the VT-d alignment w/a in
plane->min_alignment() which means that panning inside a larger
framebuffer can still cause the plane SURF to be misaligned.
Fix the issue by moving the VT-d alignment w/a into
plane->min_alignment() itself (for the affected platforms).
