PCI: Add ACS quirk for Wangxun NICs
[ Upstream commit a2b9b123ccac913e9f9b80337d687a2fe786a634 ]
Wangxun has verified there is no peer-to-peer between functions for the
below selection of SFxxx, RP1000 and RP2000 NICS. They may be
multi-function devices, but the hardware does not advertise ACS capability.
Add an ACS quirk for these devices so the functions can be in independent
IOMMU groups.
