ppc/pnv: attach phb3/phb4 root ports in QOM tree 

At this moment we leave the pnv-phb3(4)-root-port unattached in QOM:

  /unattached (container)
(...)
    /device[2] (pnv-phb3-root-port)
      /bus master container[0] (memory-region)
      /bus master[0] (memory-region)
      /pci_bridge_io[0] (memory-region)
      /pci_bridge_io[1] (memory-region)
      /pci_bridge_mem[0] (memory-region)
      /pci_bridge_pci[0] (memory-region)
      /pci_bridge_pref_mem[0] (memory-region)
      /pci_bridge_vga_io_hi[0] (memory-region)
      /pci_bridge_vga_io_lo[0] (memory-region)
      /pci_bridge_vga_mem[0] (memory-region)
      /pcie.0 (PCIE)

Let's make changes in pnv_phb_attach_root_port() to attach the created
root ports to its corresponding PHB.

This is the result afterwards:

    /pnv-phb3[0] (pnv-phb3)
      /lsi (ics)
      /msi (phb3-msi)
      /msi32[0] (memory-region)
      /msi64[0] (memory-region)
      /pbcq (pnv-pbcq)
    (...)
      /phb3_iommu[0] (pnv-phb3-iommu-memory-region)
      /pnv-phb3-root.0 (pnv-phb3-root)
        /pnv-phb3-root-port[0] (pnv-phb3-root-port)
          /bus master container[0] (memory-region)
          /bus master[0] (memory-region)
          /pci_bridge_io[0] (memory-region)
          /pci_bridge_io[1] (memory-region)
          /pci_bridge_mem[0] (memory-region)
          /pci_bridge_pci[0] (memory-region)
          /pci_bridge_pref_mem[0] (memory-region)
          /pci_bridge_vga_io_hi[0] (memory-region)
          /pci_bridge_vga_io_lo[0] (memory-region)
          /pci_bridge_vga_mem[0] (memory-region)
          /pcie.0 (PCIE)
