I haven't read through this in detail yet, but wanted to make sure that
the DT representation can handle nested power domains. At least
SH-mobile has a hierarchy of power domains and the genpd code can handle
that, so wanted to make sure that the DT representation can handle it as
well.
Thanks,
Kevin
