drm/i915: Add support for variable cursor size on 845/865
845/865 support different cursor sizes as well, albeit a bit differently
than later platforms. Add the necessary code to make them work.
Untested due to lack of hardware.
v2: Warn but accept invalid stride (Chris)
Rewrite the cursor size checks for other platforms (Chris)
v3: More polish and magic to the cursor size checks (Chris)
v4: Moar polish and a comment (Chris)
