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
the specific PHB is ready to supply EEH service.
