Commit eda8c286 ("iommu/amd: Enable device ATS/PASID/PRI capabilities
independently") changed the way it enables device capability while
attaching devices. I missed to account the attached domain capability.
Meaning if domain is not capable of handling PASID/PRI (ex: paging
domain with v1 page table) then enabling device feature is not required.

This patch enables PASID/PRI only if domain is capable of handling SVA.
Also move pci feature enablement to do_attach() function so that we make
SVA capability in one place. Finally make PRI enable/disable functions as
static functions.
