Jon Hunter are working on adding robust method to be able to remove
initialized genpds [1].

In that series we intend to remove the __of_genpd_add_provider() API,
and instead only have of_genpd_add_provider_onecell() and
of_genpd_add_provider_simple(). Could you please convert to use any of
these APIs instead?

Kind regards
Uffe
