[PATCH] PCI Hotplug: rpaphp: set eeh option (enabled ) prior to any i/o to newly added IOA

Attached patch fix the problem I have found during DLPAR I/O slots
testing on our new hardware.  rpaphp needs to set eeh-option(eanbled)
for newly added IOA prior to performing PCI config(pci_setup_device),
otherwise the pci_dev of the IOA will have invalid base address
information.

Linas Vepstas impleted eeh changes.
