Hi all,

there are a bunch of IOMMU APIs that are entirely unused, or only used as
a private communication channel between the FSL PAMU driver and it's only
consumer, the qbman portal driver.

So this series drops a huge chunk of entirely unused FSL PAMU
functionality, then drops all kinds of unused IOMMU APIs, and then
replaces what is left of the iommu_attrs with properly typed, smaller
and easier to use specific APIs.
