I would rather get rid of struct hw_pci for architecture independent drivers and add a different registration method on arm32 that is compatible with what we come up with on arm64. The main purpose of hw_pci is to allow multiple PCI controllers to be initialized at once, but we don't actually need that for any of the "modern" platforms where we already have a probe function that gets called once for each controller.

No. The main purpose of hw_pci is as a container to support multiple different platform specific PCI implementations in one kernel. It's exactly what you need for single zImage.
