drm/i915: Add WA for planes ending close to left screen edge
While running the kms_plane clipping test I noticed a similar problem to
the one described in Display WA #1175. In this case, similarly for
planes other than the cursor, with 1 or 3 pixels visible from the left
edge of the screen to the end of the plane and an odd plane X offset
used for clipping causes the same kind of underflow and display
corruption as described for WA #1175. Fix this in a similar way as that
WA rejecting planes ending <4 pixels from the left screen edge.
v2:
- Rebase on v2 of patch 1/1.
