powerpc/eeh: Refactor to use pci_dn
Currently, EEH depends on device_node or pci_dev heavily. Unfortunately,
SRIOV VFs are supported depending on pci_dn heavily, which is conflicting
with EEH implementation. In order for better support EEH on SRIOV VF, the
EEH is better to be changed a bit to depend on pci_dn, which is exactly
what the patchset does.
The patchset is expected to merged after the patchset "EEH cleanup to
remove chip layer for PowerNV", before "SRIOV patchset". The first two
patches are extracted from SRIOV patchset to make this patchset
self-contained.
Changelog
=========
v1 -> v2:
* Remove SRIOV PF/VFs related logics in pci_dn.c and the flag for
VF's pci_dn in pci-bridge.h;
* Dereference "struct pci_dn *pci_data", not "void *firmware_data"
from "struct dev_archdata" and "struct pci_controller";
* Move changes to eeh_restore_dev_state() from PATCH[7/7] to
PATCH[6/7] to avoid build error caused by PATCH[6/7];
