This comes from the early design of the generic PM domain, thus I
assume we have some HW with such complex PM topology. However, I don't
know if it is actually being used.

Moreover, the corresponding DT bindings for "power-domains" parents,
can easily be extended to cover more than one parent. See more in
Documentation/devicetree/bindings/power/power_domain.txt

Kind regards
