powerpc/powernv: Only clear EEH freeze for some errors

Only clear an EEH freeze if an error occurs. However, if an OPAL_HARDWARE
error is returned, this indicates a hardware failure which cannot be
unfrozen, and instead needs a hardware reset. Attempting to unfreeze a
broken PCH will result in console spam for each attempt. To avoid the spam,
just don't do it.
