From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>
Split intel_atomic_commit_tail() into a lower level function that does
the actual commit, and a higher level one that waits for the
dependencies and signals the commit as done. We'll reuse the lower
level function to perform commits during GPU resets.
