Shouldn't we be reusing the dev.of_node field to look this information
up? On Tegra we do register the MSI chip and set the dev member to the
PCIe host bridge device. Can't the same thing be done for the Armada?
I assume that the MSI controller provider will be instantiated from the
device tree and hence there will already be a struct platform_device and
therefore also a struct device associated with it which should have the
of_node field set to the correct value automatically.
