It is an additional function pointer in iommu_ops and replaces the
add_device callback for IOMMUs that are DT-enabled.
The idea is that we can have a single function that sets up DMA
for the device properly, including iommus when they are configured,
and it lets us pass the necessary parameters describing the setup
of the master device into the iommu driver.
