Add label to the first cpu so that it can be referenced
from derived dts files.

Can you also set the cpu clock here? It is part of the SoC
and does not belong in the board DTS files.
Do you mean operating-points, or something else? Different SBCs will
probably require different combinations of operating points just for
safety's sake, because they have different regulators and [some have
botched] thermal designs, so it might make sense to customize it for
differnt boards, and I don't feel adventurous enough setting it for all
H3 boards out there.

Or is this comment related to the missing cpu clock rate message I see
on every boot?

[    0.058912] /cpus/cpu at 0 missing clock-frequency property

  Ondrej
Otherwise this one looks good.
