[Skiboot] [PATCH 1/4] platforms/ibm-fsp/firenze: Fix PCI slot power-off pattern

[Gavin Shan]

When powering off the PCI slot, the corresponding bits should
be set to 0bxx00xx00 instead of 0bxx11xx11. Otherwise, the
specified PCI slot can't be put into power-off state. Fortunately,
it didn't introduce any side-effects so far.
