[PATCH v2, part 1 9/9] PCI, unicore, m68k: remove redundant call of pci_bus_add_devices()

pci_scan_bus() and pci_scan_root_bus() has called pci_bus_add_devices() once, so remove the redundant call of pci_bus_add_devices(). On the other handle, subsys_init() callbacks will be invoked before device_init() callbacks, so it should be safe to remove the redundant calls. Signed-off-by:
