[PATCH v10 22/29] parisc/PCI: Use pci_scan_root_bus() for simplicity

[Yijing Wang]

From: Yijing Wang <wangyijing0307@xxxxxxxxx>

Now pci_bus_add_devices() has been ripped out
from pci_scan_root_bus(), we could use pci_scan_root_bus()
instead of pci_create_root_bus() + pci_scan_child_bus()
for simplicity.
