devicetree: Add nx node to power9-phb4.dts
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.
#address-cells = <0>;
#interrupt-map-mask = < 0xff >;
