Since old kernel versions wouldn't expose the IN_FORMATS_ASYNC blob, userspace can't really use the absence of the blob to determine that async flips aren't supported. Thus it seems better to always expose the blob on all planes, whether they support async flips or not. The blob will simply not indicate any format+modifier combinations as supported on planes that aren't async flip capable. Currently we expose the blob for all skl+ universal planes (even though we implement async flips only for the first plane on each pipe), and i9xx primary planes (for ilk+ we have async flips support, for pre-ilk we do not). Complete the full set by also expsosing the blob on pre-skl sprite planes, and cursors.
