drm/syncobj: Drop add/remove_callback from driver interface
This is used for handling future fences. Currently no driver use
these, and I think given the new timeline fence proposed by KHR it
would be better to have a more abstract interface for future fences.
Could be something simple like a struct dma_future_fence plus a
function to add a callback or wait for the fence to materialize.
Then syncobj (and anything else really) could grow new functions to
expose these two drivers. Normal dma_fence would then keep the nice
guarantee that they will always signal (and through ordering, be
deadlock free). dma_future_fence would then be the tricky one.
This also fixes sphinx complaining about the kerneldoc.
