Aneesh Kumar K.V 467b171af8 mm/demotion: update node_is_toptier to work with memory tiers 
With memory tier support we can have memory only NUMA nodes in the top
tier from which we want to avoid promotion tracking NUMA faults.  Update
node_is_toptier to work with memory tiers.  All NUMA nodes are by default
top tier nodes.  With lower(slower) memory tiers added we consider all
memory tiers above a memory tier having CPU NUMA nodes as a top memory
tier
