[PATCH v5 02/13] soc: renesas: rcar-sysc: Fix uninitialized error code in rcar_sysc_pd_init()

[Geert Uytterhoeven]

On success, rcar_sysc_pd_init() returns an uninitialized error code.
Use the return value of of_genpd_add_provider_onecell() to fix this.

This went unnoticed, as early_initcall() doesn't care about the return
value.
