drm/amd/display: disallow cropping for cursor plane

Browse source

Looking at handle_cursor_update, it doesn't seem like src_{x,y,w,h}
are picked up by DC. I also tried to change these parameters via a
test KMS client, and amdgpu ignored them. Instead of displaying the
wrong result, reject the atomic commit.
