[Stefan Roese]

This patch fixes a problem recently seen on some 4xx platforms. For
example on Kilauea PCIe slot #0.

Felix, could you please test on your Kilaue with this patch applied?
It fixes the problem on my system but please report if your board
now boots correctly with the PCIe card plugged into both slots.

Thanks.
