Subject: [PATCH v3 01/12] PCI: Use device_release_driver in pci_stop_root_bus

To be consistent with change in
| PCI: Move device_del() from pci_stop_dev() to pci_destroy_dev()

Use device_release_driver for root bus/hostbridge.

Also use device_unregister() in pci_remove_root_bus() instead of
device_del/put_device, that will be corresponding device_register()
for pci_create_root_bus for hostbridge.
