powerpc/pci: Fix SRIOV not building without EEH enabled
On Book3E CPUs (and possibly other configs), it is possible to have SRIOV
(CONFIG_PCI_IOV) set without CONFIG_EEH. The SRIOV code does not check
for this, and if EEH is disabled, pci_dn.c fails to build.
Fix this by gating the EEH-specific code in the SRIOV implementation
behind CONFIG_EEH.
Fixes: 39218cd0 ("powerpc/eeh: EEH device for VF")
