[0/1] drm/syncobj: add sideband payload

Message

Hi all,

Just explaining what is being changed here compared to v6 :

We just noticed that some of our CTS runs are flaky because when
importing a dma fence into a drm syncobj we do not update the atomic
binary payload. This leads to issues when the userspace drivers tries
to add new points to the timeline because the atomic binary payload
may then have a value inferior to the seqno of the new installed
fence.

Cheers,
