x86-64, NUMA: Kill mem_nodes_parsed
With all memory configuration information now carried in numa_meminfo, there's no need to keep mem_nodes_parsed separate. Drop it and use numa_nodes_parsed for CPU / memory-less nodes. A new helper numa_nodemask_from_meminfo() is added to calculate memnode mask on the fly which is currently used to set node_possible_map. This simplifies NUMA init methods a bit and removes a source of possible inconsistencies.
