PCI: Set Cavium ACS capability quirk flags to assert RR/CR/SV/UF

Browse source

commit 7f34267863 upstream.

The Cavium ThunderX (CN8XXX) family of PCIe Root Ports does not advertise
an ACS capability.  However, the RTL internally implements similar
protection as if ACS had Request Redirection, Completion Redirection,
Source Validation, and Upstream Forwarding features enabled.

Change Cavium ACS capabilities quirk flags accordingly.
