[Intel-gfx] [PATCH 1/2] drm/i915: Add missing scanline case for 8 cpp watermarks.

[Maarten Lankhorst]

Now that we can rotate 64 bpp formats, we need to add the rotation case.
This wasn't caught by CI or me, because the rotated formats were skipping
because the rotated watermarks exceeded the allocation limits.
