Remove the check which prevents us from hotplugging into an empty node.

Do we want to do this only for ibm,hotplug-aperture compatible ranges?

We could, but since past discussions and current testing have been unable to justify preventing hotplug to a memoryless node in the first place, I'm inclined to keep things simple.

If some edge case is discovered, making it conditional as you describe will be a good solution.

Thanks for your review! A v2 of this set is pending my investigation of Michael's suggestion to get node hotadd working.
