[PATCH 1/3] ppc32: Fix a few issues in Yucca PCIe functionality

[Ruslan V. Sushko]

This patch includes following changes:

1) Fix wrong PCIe config space address calculation for slot #3 (Using an
signed integer for port numbering will cause wrong address accessing)
2) Fix the PCI bus numbering assignment. This will be an issues if more
than one PCI card is inserted.
3) Add verbose error checking.
4) Remove commented or unused lines.
