The post initialization (struct eeh_ops::post_init) is called after the EEH probe is done. On the other hand, the EEH core post initialization is designed to call platform and then I/O chip backend on PowerNV platform. The patch adds the backend for I/O chip to notify the platform that the specific PHB is ready to supply EEH service.
