drm/amd/display: add basic atomic check for cursor plane
commit 626bf90fe03fa080d8df06bb0397c95c53ae8e27 upstream.
This patch adds a basic cursor check when an atomic test-only commit is
performed. The position and size of the cursor plane is checked.
This should fix user-space relying on atomic checks to assign buffers to
planes.
