hw/pci: Add pcie_count_ds_port() and pcie_find_port_first() helpers
These two helpers enable host bridges to operate differently depending on
the number of downstream ports, in particular if there is only a single
port.
Useful for CXL where HDM address decoders are allowed to be implicit in
the host bridge if there is only a single root port.
