Besides, bus_nr indicates the bus number of pxb-pcie under pcie.0 bus,
but since we put it into separate domain, it should be zero,
Why should it be 0? Isn't possible we start another domain from bus_nr> 0?
In the last version, I got a misunderstanding about bus_nr, and you pointed me
out that we should start from bus 0 when in new domain. I can support this
start_bus in later patch, but I wonder when would we want to start a domain
from bus_nr > 0? I'm not quite familiar with the use case.
