soc: amlogic: meson-ee-pwrc: propagate PD provider registration errors

xdarklight · khilman · commit 0766d65e6afa · 2019-12-09T15:21:20.000-08:00
of_genpd_add_provider_onecell() can return an error. Propagate the error so the driver registration fails when of_genpd_add_provider_onecell() did not work.
