Pci_host_bridge hold the domain number, we need
to assign domain number prior to root bus creation,
because root bus need to know the domain number
to check whether it's alreay exist. Also it's
preparation for separating pci_host_bridge creation
from pci_create_root_bus().

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.

Introduce pci_host_assign_domain_nr() to assign domain number
for pci_host_bridge.

* have opaque sysdata, so IA64 specific
pci_domain_nr() could get the pci_controller and return the exact
domain number, but now we use common pci_domain_nr() functions, so we
should fix this warning.

Now platform specific sysdata is saved in pci_bus,
and pcibios_root_bridge_prepare() need to know
the sysdata. Later, we would move pcibios_root_bridge_prepare()
prior to root bus creation, so we need to make
pci_host_bridge hold sysdata.

Pcibios_root_bridge_prepare() in powerpc set root bus
speed, it's not the preparation for pci host bridge.
For better separation of host bridge and root bus creation,
It's need to rename it to another weak function.

, so introduce pci_create_root_bus_generic
and pci_scan_root_bus_generic() which simply assign domain
number to -1.

Hi Yinghai, does this patch depend on the previous item
align/size: 4M/12M, 2M/6M.
and prarent bridge must align/size: 4M/20M.
So at last, we use 8M/17M as parent bridge alt_align/alt_size.

Hi Yinghai, does this patch depend on the previous items in this patchset ?
Could you provide another version
