drm/i915: Don't reject primary plane windowing with color keying enabled on SKL+

Browse source

commit 6f94b6dd00 upstream.

On SKL+ plane scaling is mutually exclusive with color keying. The code
check for this, but during some refactoring the code got changed to
also reject primary plane windowing when color keying is used. There is
no such restriction in the hardware, so restore the original logic.
