spapr: Add H-Call H_HOME_NODE_ASSOCIATIVITY
H_HOME_NODE_ASSOCIATIVITY H-Call returns the associativity domain
designation associated with the identifier input parameter
This fixes a crash when we try to hotplug a CPU in memory-less and
CPU-less numa node. In this case, the kernel tries to online the
node, but without the information provided by this h-call, the node id,
it cannot and the CPU is started while the node is not onlined.
It also removes the warning message from the kernel:
VPHN is not supported. Disabling polling..
