Hi,

AMD hardware can do more on the async flip path than just the primary plane, so
to lift up the current restrictions, this patchset allows drivers to write their
own check for planes for async flips.

For now this patchset only allow for async commits with IN_FENCE_ID and
FB_DAMAGE_CLIPS. Userspace can query if a driver supports this with TEST_ONLY
commits.

I will left overlay planes for a next iteration.

Changes from v1:
- Drop overlay planes option for now
v1: https://lore.kernel.org/dri-devel/20240116045159.1015510-1-andrealmeid@igalia.com/
