[ Upstream commit c8de8ed2dcaac82e5d76d467dc0b02e0ee79809b ] The ACS quirks differ in needless ways, which makes them look more different than they really are. Reorder the ACS flags in order of definitions in the spec: PCI_ACS_SV Source Validation PCI_ACS_TB Translation Blocking PCI_ACS_RR P2P Request Redirect PCI_ACS_CR P2P Completion Redirect PCI_ACS_UF Upstream Forwarding PCI_ACS_EC P2P Egress Control PCI_ACS_DT Direct Translated P2P (PCIe r5.0, sec 7.7.8.2) and use similar code structure in all. No functional change intended.
