From: Ville Syrjälä <[email protected]> Async flips often require bigger alignment that sync flips. Currently we have HAS_ASYNC_FLIPS() checks strewn about to inidcate that async flips are generally supported and thus we want more alignment. Switch that over to using intel_plane_can_async_flip() so that we can handle these in a slightly less messy way. Currently we don't have cases where async flips would require different alignment for different modifiers on the same plane.
We'll also move the HAS_ASYNC_FLIPS() check to the plane init code so that we can still use that as a quick way to disable the async flips workarounds for testing purposes.
