PCI: Simplify pcie_bus_configure_settings() interface
Based on a patch by Jon Mason (see URL below).
All users of pcie_bus_configure_settings() pass arguments of the form
"bus, bus->self->pcie_mpss". The "mpss" argument is redundant since we
can easily look it up internally. In addition, all callers check
"bus->self" for NULL, which we can also do internally.
This patch simplifies the interface and the callers. No functional change.
