iommu/vt-d: Refactor the pasid setup helpers

Browse source

It is clearer to have a new set of pasid replacement helpers other than
extending the existing ones to cover both initial setup and replacement.
Then abstract out the common code for manipulating the pasid entry as
preparation.

No functional change is intended.
