ppc4xx: Add pci_pre_init() for 405 boards
This patch removes the CFG_PCI_PRE_INIT option completely, since
it's not needed anymore with the patch from Matthias Fuchs with
the "weak" pci_pre_init() implementation.

The default 440GP PCI target configuration is minimal -- it assumes that
the strapping registers are set as necessary. Since the strapping bits
