powerpc/eeh: I/O chip next error

The patch implements the backend for EEH core to retrieve next
EEH error to handle. For the informational errors, we won't bother
the EEH core. Otherwise, the EEH should take appropriate actions
depending on the return value:

0 - No further errors detected
1 - Frozen PE
2 - Fenced PHB
3 - Dead PHB
4 - Dead IOC
