drm/nouveau/core: convert event handler apis to split create/enable semantics
This is a necessary step towards being able to work with the insane locking
requirements of the DRM core's vblank routines, and a nice cleanup as a
side-effect.
This is similar in spirit to the interfaces that Peter Hurley arrived at
with his nouveau_event rcu conversion series.
