drm/amdgpu: Add wait IOCTL timeline syncobj support
Add user fence wait IOCTL timeline syncobj support.
v2:(Christian)
- handle dma_fence_wait() return value.
- shorten the variable name syncobj_timeline_points a bit.
- move num_points up to avoid padding issues.
v3:(Christian)
- Handle timeline drm_syncobj_find_fence() call error
handling
- Use dma_fence_unwrap_for_each() in timeline fence as
there could be more than one fence.
v4:(Christian)
- Drop the first num_fences since fence is always included in
the dma_fence_unwrap_for_each() iteration, when fence != f
then fence is most likely just a container.
v5: Added Alex RB to merge the kernel UAPI changes since he has
already approved the amdgpu_drm.h changes.
