Additionally, to support such a scenario, we can no longer retain the simple dynamic allocation API we have today, because it might end up allocating dspB an hwlock from IckA. We will have to make sure hwlocks are allocated only from pools visible to the user, something that will change not only the hwspinlock API but also the way it maintains the hwlocks. I suspect we want to wait for such hardware to show up first, and only then add framework support for it. Regardless, we obviously do want to make sure our DT binding is prepared for the worse, so we'll drop the "base-id" field.
