PCI: Include PCI-to-PCIe bridges as "Downstream Ports"
A PCI/PCI-X to PCI Express bridge, sometimes referred to as a "reverse bridge", is a bridge with conventional PCI or PCI-X on its primary side and a PCI Express Port on its secondary (downstream) side. That PCIe Port is a Downstream Port and could be connected to a slot, just like a Root Port or a Switch Downstream Port. Make pcie_downstream_port() return true for them, so we can access the Slot registers in the PCIe capability. Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
