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

Hey Sasha,
Technically this is an optional property so I didn't mark any of
the patches as CC: stable as they not really fixes. The plan to is
to fix the hwloc problem at the source rather than papering over it
with the dts:
https://lore.kernel.org/linux-riscv/20220715175155.3567243-1-mail@xxxxxxxxxxx/

Those patches are delayed until after -rc1 as they weren't reviewed
from the riscv side prior to the arm64 tree closing, but the plan is
to backport those instead.

I suppose there's no harm having these too, but I'll leave that up
to the better judgement of others... What do you (plural) think?

I'll just drop these. Feel free to send us a note when the fix is
ready...
