ppc4xx: Consolidate 4xx PCIe board specific configuration

This patch consolidates the PPC4xx board specific PCIe configuration
code. This way the duplicated code is removed. Boards can implement a
special, non standard behaviour (e.g. number of PCIe slots, etc) by
overriding the weak default functions.
