sb/intel/bd82x6x: Warn about slow PCIe downstream devices

Warn when a device took longer than usual to appear.
Use the PDS bit to detect if a root port has a downstream
device connected and warn if enumeration failed.

Test: On Lenovo X220 all PCIe device are visible, thus the
      added code path is never taken.
