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. Signed-off-by: Stefan Roese <sr@denx.de>
