I made changes to rpaphp code, so it can handle multi-fuction
devices correctly. The problem is that the pci_dev field of slot struct
can only record one pci_dev of  the devices of a multi-fuction card.  I
changed pci_dev (a single pci_dev type pointer) to pci_funcs( a list of
pci_dev type pointers). I  rewrote some of the config/unconfig code to
support  the slot struct change.

Along with above changes,  I added LDRSLOT(logical I/O slot) support.
We need LDRSLOT support for DLPAR I/O.  A card in a LDRSLOT can't be
physically removed, but can be logically removed  from one partiton and
reassinged to another partition.

I also merged rpaphp changes from ames tree.
