I'm in a similar situation, except I'm using PCI instead of PCIe. I've tried both removing the PCI interface from the dts, and disabling CONFIG_PCI. Both work fine. You probably don't want to leave the PCI interface in the dts and also leave CONFIG_PCI enabled. I ran into some really strange issues this way... (Linux ran through the quirks and tried to re-initialize a network card, even though the driver was disabled, etc.) I think the suggested way is to remove the PCI interface from the dts, that way you can potentially share a kernel between similar boards with and without PCI root interfaces, just by changing the dts.
