PCI: Add ACS quirk for Qualcomm SA8775P
[ Upstream commit 026f84d3fa62d215b11cbeb5a5d97df941e93b5c ]
The Qualcomm SA8775P root ports don't advertise an ACS capability, but they
do provide ACS-like features to disable peer transactions and validate bus
numbers in requests.
Thus, add an ACS quirk for the SA8775P.
