iommu/vt-d: Consolidate the struct dev_pasid_info add/remove

Browse source

The domain_add_dev_pasid() and domain_remove_dev_pasid() are added to
consolidate the adding/removing of the struct dev_pasid_info. Besides,
it includes the cache tag assign/unassign as well.

This also prepares for adding domain replacement for pasid. The
set_dev_pasid callbacks need to deal with the dev_pasid_info for both old
and new domain. These two helpers make the life easier.

intel_iommu_set_dev_pasid() and intel_svm_set_dev_pasid() are updated to
use the helpers.
