Sorry, the topic you are working on is over my head.
Catching gEfiPciIoProtocolGuid (with a protocol notify registration) is
definitely wrong, from a UEFI driver model perspective.
EFI_PCI_PLATFORM_PROTOCOL *could* be what you are afrer. I recommend
reading through Chapter 11, "PCI Platform", in Volume 5 of the Platform
Init spec (latest release is, to my knowledge, v1.7). Chapter 10 could
be relevant too ("PCI Host Bridge").
I think the PCI maintainers in edk2 could be of more help than I; please
see Hao and Ray in Maintainers.txt.
Thanks
Laszlo
