powerpc/eeh: pseries platform config space access in EEH
With the original EEH implementation, the access to config space of the corresponding PCI device is done by RTAS sensitive function. That depends on pci_dn heavily. That would limit EEH extension to other platforms like powernv because other platforms might have different ways to access PCI config space. The patch splits those functions used to access PCI config space and implement them in platform related EEH component. It would be helpful to support EEH on multiple platforms simutaneously in future.
