[POWERPC] 4xx: Add 460EX PCIe support to 4xx pci driver
All this code is needed to properly initialize the 460EX PCIe host bridge(s). We re-initialize all ports again, even though this has been done in the bootloader (U-Boot) before. This way we make sure, that we always run the latest init code in Linux and don't depend on code versions from U-Boot. Unfortunately all IBM/AMCC chips currently supported in this PCIe driver need a different reset-/init-sequence. Tested on AMCC Canyonlands eval board.
