PCI: Add device-specific ACS Redirect disable infrastructure
Intel Sunrise Point (SPT) PCH hardware has an implementation of the ACS bits that does not comply with the PCIe standard. To deal with this we need device-specific quirks to disable ACS redirection. Add a new pci_dev_specific_disable_acs_redir() quirk and a new .disable_acs_redir() function pointer for use by non-compliant devices. No functional change intended. Signed-off-by: Logan Gunthorpe <logang@deltatee.com> [bhelgaas: split to separate patch, move pci_dev_specific_disable_acs_redir() declarations to drivers/pci/pci.h] Signed-off-by: Bjorn Helgaas <bhelgaas@google.com> Reviewed-by: Alex Williamson <alex.williamson@redhat.com>
