When pcie-root-port parameter is used to link virtual pcie RP with
physical RP, they should have the same bridge window size.

On ManaTEE, each physical pcie root port has a virtual pcie root port in
CrOS, this commit links virtual RP to physical RP. The following virtual
RP's config registers are from physical:
--devie ID
--device type
--bridge bus range

Currently bridge's PciAddress is allocated from system bus allocator,
but when virtual pcie root port is linked to physical pcie root port,
its PciAddress should be same as physical pcie RP, so thid commit let
bridge get its PciAddress from the backend pcie RP device, this is
convenient for later pcie root port.
This commit doesn't change function.

Currently pci bridge's bus range is managed in pci bridge structure, but
when virtual pcie root port is linked to physical pcie root port, the bus
range of virtual pcie RP should be same as physical pcie RP, so this commit
let bridge get its bus range from the backend pcie root port device, this
