dma-fence: Use a flag for 64-bit seqnos
With the goal of reducing the need for drivers to touch (and dereference)
fence->ops, we move the 64-bit seqnos flag from struct dma_fence_ops to
the fence->flags.
Drivers which were setting this flag are changed to use new
dma_fence_init64() instead of dma_fence_init().
v2:
* Streamlined init and added kerneldoc.
* Rebase for amdgpu userq which landed since.
