There are more paths that need to flush cache for present pasid entry after adding pasid replacement. Hence, add a helper for it. Per the VT-d spec, the changes to the fields other than SSADE and P bit can share the same code. So intel_pasid_setup_page_snoop_control() is the first user of this helper. No functional change is intended.
