[PATCH 2/3] PCI: Add DMA configuration for virtual platforms
...astructure is

Urgh, it's already been established[1] that having IOMMU setup tied to
DMA configuration at driver probe time is not just conceptually wrong
but actually broken, so the concept here worries me a bit. In a world
where of_iommu_configure() and friends are being called much earlier
around iommu_probe_device() time, how badly will this fall apart?
