Looks great for the most part. I've looked through the whole driver
again, and I have two small issues remaining:

a) Please clarify in the changeset description why there is no support
for PCI I/O space.

b) I think you should use the 'msi-parent' property, and the
of_pci_find_msi_chip_by_node() to find the msi_chip for the
PCI controller. This will make it possible to forward MSIs
to the main interrupt controller in the system, which is more
efficient. See the pcie-mvebu driver for an example of this.

Other than these:
