[Skiboot] [PATCH 3/6] devicetree: Add nx node to power9-phb4.dts

[Reza Arbab]

A (non-qemu) p9 without an nx node will assert in p9_darn_init():

  dt_for_each_compatible(dt_root, nx, "ibm,power9-nx")
          break;
  if (!nx) {
          if (!dt_node_is_compatible(dt_root, "qemu,powernv"))
                assert(nx);
          return;
  }

Since NX is this essential, add it to the device tree.
