[0/2] drm/i915: timeline semaphore support

Hi all,

This series implement required changes to support Vulkan timeline
semaphores. Mesa's Anv driver will make use of this, unfortunately we
can't disclose the userspace changes yet.

Hoping we can bend the rules a bit (like for the drm-syncobj changes
landed already), so that we can be compliant on the first day the
Vulkan spec is released.

Cheers,
