powerpc/pseries: Consolidate different NUMA distance update code paths
The associativity details of the newly added resourced are collected from the hypervisor via "ibm,configure-connector" rtas call. Update the numa distance details of the newly added numa node after the above call. Instead of updating NUMA distance every time we lookup a node id from the associativity property, add helpers that can be used during boot which does this only once. Also remove the distance update from node id lookup helpers. Currently, we duplicate parsing code for ibm,associativity and ibm,associativity-lookup-arrays in the kernel. The associativity array provided by these device tree properties are very similar and hence can use a helper to parse the node id and numa distance details.
