Chris Wilson 52e68630d1 drm/i915: Fix offset page-flips on i965+
i965 uses the Display Registers to compute the offset from the display
base so the new base does not need adjusting when flipping. The older
chipsets use a fence to access the display and so do perceive the
surface as linear and have a single base register which is reprogrammed
using the flip.
