Subject: [PATCH] drm/msm: Expose DRIVER_SYNCOBJ_TIMELINE

From: Rob Clark <robdclark@...omium.org>

Initially we didn't want to expose the cap, as it would expose a bug
in the vk driver (turnip) with older mesa versions.  This was fixed over
a year ago (and cherry-picked to stable release branches at the time),
see https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/25981.
So let's go ahead and expose it now.
