DRM/i915: only use tiled blits on 965+

When scheduled swaps occur, we need to blit between front & back
buffers.  If the buffers are tiled, we need to set the appropriate
XY_SRC_COPY tile bit, but only on 965 chips, since it will cause
corruption on pre-965 (e.g. 945).

Bug reported by and fix tested by Tomas Janousek <tomi@nomi.cz>.
