powerpc/cell/iommu: Improve error message for missing node
Some devices don't have a correct node ID and thus can't be attached to an iommu. The message displayed by the iommu code isn't very useful if you don't have a device-tree node as it tries to print the device-tree path but not the struct device name. Improve this by printing the device name as well. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
