MIPS: sgi-ip27: make NODE_DATA() the same as on all other architectures
sgi-ip27 is the only system that defines NODE_DATA() differently than the
rest of NUMA machines.
Add node_data array of struct pglist pointers that will point to
__node_data[node]->pglist and redefine NODE_DATA() to use node_data array.
This will allow pulling declaration of node_data to the generic mm code in
the next commit.
