[Qemu-ppc] [PULL 36/36] sPAPR: Enable EEH on VFIO PCI device only

[David Gibson]

From: Gavin Shan <address@hidden>

This checks if the PCI device retrieved from the PCI device address
is VFIO PCI device when enabling EEH functionality. If it's not
VFIO PCI device, the EEH functonality isn't enabled.
