PCI: Add ACS quirk for Qualcomm Hamoa & Glymur

[ Upstream commit 44d2f70b1fd72c339c72983fcffa181beae3e113 ]

The Qualcomm Hamoa & Glymur 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.

Add an ACS quirk for Hamoa & Glymur.
