PCI: mvebu: Support a bridge with no IO port window
Make pcie-io-aperture and the IO port MBUS ID in ranges optional. If not
provided the bridge reports to Linux that IO space mapping is not supported
and refuses to configure an IO MBUS window.
This allows both complete disable (do not specify pcie-io-aperture) and
per-port disable (do not specify a IO target ranges entry for the port).
Most PCIe devices these days do not require IO support to function, so
having an option to disable it in the driver is useful.
