x86-64, NUMA: Kill mem_nodes_parsed

Browse source

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.
