Sometimes, the bus resource start number is not equal to
root bus number. For example, in pci_scan_bus(), we always
add the default bus resource which start bus number is 0,
but the root bus number callers given may != 0, so
we need to update pci_host_bridge bus resource
complete. But pci scan
functions won't return the actual max bus number.
So we could use pci_bus_child_max_busnr() to find
that.

Mvebu_pcie_scan_bus() is not necessary, we could use
pci_common_init_dev() instead of pci_common_init(),
and pass the device pointer as the parent. Then
pci_scan_root_bus() will be called to scan the pci busses.

Now no one use weak pcibios_root_bridge_prepare() and

Now we save the domain number in pci_host_bridge,
we could remove pci_bus_assign_domain_nr() and
clean the domain member in pci_bus. Also move
pci_host_assign_domain_nr() to drivers/pci/host-bridge.c
for simplicity.

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.
