Pull PCI fixes from Bjorn Helgaas:
 "These are more fixes I'd like to have in v4.4.  Several for the Altera
  driver added for v4.4, and one for an MSI domain problem that affects
  several arm64 platforms:

  MSI:
   - Only use the generic MSI layer when domain is hierarchical (Marc
     Zyngier)

  Altera host bridge driver:
   - Fix loop in tlp_read_packet() (Dan Carpenter)
   - Fix Requester ID for config accesses (Ley Foon Tan)
   - Check TLP completion status (Ley Foon Tan)
   - Fix error when INTx is 4 (Ley Foon Tan)"
