(caveat; I've not looked at the code yet)

I had expected that PCI host controllers would be discovered via the
existing device model stuff and compatible string matching, e.g.
DT_DEVICE_START(some_pcihost, "SOME PCI HOST CONTROLLER", DEVICE_PCIBUS)
which would reference a set of compatible strings and a probe function,
the probe function would then call some pci bus registration function to
hook that bus into the system.
