[PATCH 5/5] PCI: ibmphp: Remove unused assignments

[Bjorn Helgaas <helgaas@kernel.org>]

From: Bjorn Helgaas <bhelgaas@google.com>

Remove variables and assignments that are never used.

Found by Krzysztof Wilczyński <kw@linux.com> using cppcheck, e.g.:

  $ cppcheck --enable=all --force
  unreadVariable drivers/pci/hotplug/ibmphp_res.c:1958 Variable 'bus_sec' is assigned a value that is never used.
