perf tools: Add mem2node object
Adding mem2node object to allow the easy lookup of the node for the
physical address.
It has following interface:
int mem2node__init(struct mem2node *map, struct perf_env *env);
void mem2node__exit(struct mem2node *map);
int mem2node__node(struct mem2node *map, u64 addr);
The mem2node__toolsinit initialize object from the perf data file
MEM_TOPOLOGY feature data. Following calls to mem2node__node will return
node number for given physical address. The mem2node__exit function
frees the object.
