spapr: replace numa_get_node() with lookup in pc-dimm list

Browse source 
SPAPR is the last user of numa_get_node() and a bunch of
supporting code to maintain numa_info[x].addr list.

Get LMB node id from pc-dimm list, which allows to
remove ~80LOC maintaining dynamic address range
lookup list.

It also removes pc-dimm dependency on numa_[un]set_mem_node_id()
and makes pc-dimms a sole source of information about which
node it belongs to and removes duplicate data from global
numa_info.
