If that's the case, then we should *definitely* have that IOMMU_PASID
kind of config option.

Then IOMMU_SVA - that needs PASID - can "select" it, but any other use
- that doesn't bother about SVA but might want PASID for its own
nefarious purposes - can also select it.

This is why we have config options. Not just for legibility, but also
for "there are different scenarios".
