I think the "# Remote Chip PCIe" definitions also need to be removed.
Unrelated to this, but it seems there are some hard-coded PCI values at
https://github.com/tianocore/edk2-platforms/blob/master/Platform/ARM/N1Sdp/ConfigurationManager/ConfigurationManagerDxe/ConfigurationManager.c#L1050
that are also defined as Pcds. Would it be possible to replace the hard coded values ?
