As we now have valid PCI host bridge device reference we can introduce code that is going to find its bus domain number using ACPI _SEG method.
Note that _SEG method is optional, therefore _SEG absence means that all PCI buses belong to domain 0.
While at it, for the sake of code clarity we put ACPI and DT domain assign methods into the corresponding helpers.
In my patchset, I had a slightly different and I think better approach for this without calling the _SEG method again. Please see http://www.spinics.net/lists/arm-kernel/msg478167.html at the last part of http://www.spinics.net/lists/arm-kernel/msg478169.html
