[PATCH AUTOSEL 5.15 10/28] riscv: dts: sifive: Add fu740 topology information

From: Conor Dooley <conor.dooley@microchip.com>

[ Upstream commit bf6cd1c01c959a31002dfa6784c0d8caffed4cf1 ]

The fu740 has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.
