PCI: Add quirk for known incorrect MPSS
Using legacy interrupts and TLPs > 256 bytes on the SFC4000 (all revisions) may cause interrupt messages to be replayed. In some systems this results in a non-recoverable MCE. Early boards using the SFC4000 set the maximum payload size supported (MPSS) to 1024 bytes and we should override that. There are probably other devices with similar issues, so give this quirk a generic name.
