drm/atomic: Allow userspace to use damage clips with async flips

[ Upstream commit f85de245c6a8e2654e1e9158588bcf78e38cd5a5 ]

Allow userspace to use damage clips with atomic async flips. Damage
clips are useful for partial plane updates, which can be helpful for
clients that want to do flips asynchronously.

Fixes: 0e26cc72c71c ("drm: Refuse to async flip with atomic prop changes")
