The kernel test robot reports that various drivers have an undefined reference to stmmac_simple_pm_ops. This is caused by EXPORT_SYMBOL_GPL_SIMPLE_DEV_PM_OPS() defining the struct as static and omitting the export when CONFIG_PM=n, unlike DEFINE_SIMPLE_PM_OPS() which still defines the struct non-static. Switch to using DEFINE_SIMPLE_PM_OPS() + EXPORT_SYMBOL_GPL(), which means we always define stmmac_simple_pm_ops, and it will always be visible for dwmac-* to reference whether modular or built-in.
