should be a fixup to the original commit adding display. When we rebase
we will have conflicts since the locks were moved around, but I don't
think we have much option other than fixing the conflicts when they
happen. It's a downside of the rebasing branch.

Ideally in the final state when the i915 side of the refactors is
completed, we will just not have to init any lock here as it would be
as part of the display init on the i915 side.
