I'm not sure ibm,current-associativity-domains is guaranteed to exist on older
firmware. You may need check that it exists and fall back to
ibm,max-associativity-domains in the event it doesn't

Yes. Looks like it's a PowerVM-specific property.

Right, this is just a PowerVM specific property and doesn't affect PowerNV.
On PowerNV thought we have sparse nodes, the max possible nodes is set
correctly.
