If we know that a device has broken parity checking, then disable it.
This avoids quirks like in r8169 where on the first parity error
interrupt parity checking will be disabled if broken_parity_status
is set. Make pci_quirk_broken_parity() public so that it can be used
by platform code, e.g. for Thecus N2100.

  r8169: simplify broken parity handling now that PCI core takes care
