Do we need some locking here?
bind_context_ready is changed in suspend/resume or after mod probe so no need to
worry about locking here.

Can you put all this part in patch 4 or make it a separate patch?
This patch contains the new member intel_engine_cs->bind_context_ready
which is why I added these two function in this.
Probably it makes sense to move only i915_ggtt_require_binder() out of
this patch ?
