[PATCH AUTOSEL 5.18 13/39] riscv: dts: canaan: Add k210 topology information

[Sasha Levin]

From: Conor Dooley <conor.dooley@xxxxxxxxxxxxx>

[ Upstream commit d9d193dea8666bbf69fc21c5bdcdabaa34a466e3 ]

The k210 has no cpu-map node, so tools like hwloc cannot correctly
parse the topology. Add the node using the existing node labels.
