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.
