In the case of the EDAC driver there isn't any ACPI declaration.  It just does
pci_get_device() to find the devices it needs to use with a lookup based on
vendor-id and device-id.

and then uses	pci_read_config_dword() to read various offsets from config
space, some of which are in PCIe extended config space.
