Now we can remove the deprecated pci_scan_bus_parented(),
and use pci_scan_root_bus() instead.

Now we could use pci_scan_root_bus() instead of
pci_scan_bus(), pass NULL resources means use the default

Pci_scan_root_bus(), pci_scan_bus() and pci_scan_bus_parented()
are very similar. But the latter two use the default
io/mem resources. Enhance pci_scan_root_bus() to support
default io/mem resources, then we could use
pci_scan_root_bus() instead of them, and clean them up
Now we could use pci_scan_host_bridge() to refactor
pci_acpi_scan_root().

Now pci_host_bridge has been ripped out from pci root
bus creation. Currently pci_scan_root_bus() lacks
scalability, so platform host drivers have no proper
way to configure pci_host_bridge. E.g we should assign
msi_controller to pci_host_bridge, add argument for
strictly speaking pci_bus_add_devices()
should be called after the resources assignment.
