Subject: [PATCH 4/4] clk: renesas: cpg-mssr: propagate return value of_genpd_add_provider_simple()

of_genpd_add_provider_simple() might fail, this patch makes sure we check
the return value of of_genpd_add_provider_simple() by propagating the
return value to the caller of cpg_mssr_add_clk_domain().
