PCI: Clear PAPR error injection
Though the p7ioc spec states the errors triggered by PAPR error
injection register set (0x2b0, 0x2b8, 0x2c0) should be one-shot
without "sticky" bit, Firebird-L machine doesn't follow the rule.
It will cause endless frozen PE until we have to remove the PE
permanently.
The patch extends opal_pci_reset() allowing kernel to clear PAPR
error injection register set at appropriate point.
