[PATCH 5.4 003/222] soc: amlogic: meson-ee-pwrc: propagate PD provider registration errors

From: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

commit 0766d65e6afaea8b80205a468207de9f18cd7ec8 upstream.

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.
