[PATCH AUTOSEL 5.19 08/48] riscv: dts: microchip: Add mpfs' topology information

[Sasha Levin]

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

[ Upstream commit 88d319c6abaeb37f0e2323275eaf57a8388e0265 ]

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