ppc4xx: Consolidate pci_pre_init() function
This patch removes the duplicted implementations of the pci_pre_init() function by introducing a weak default function for it. This weak default has a different implementation for some PPC variants. It can be overridden by a board specific version. Signed-off-by: Stefan Roese <sr@denx.de>
