When the legacy and iommufd backends were introduced, a set of common
vfio-pci routines were exported in pci.c for both backends to use :
vfio_pci_pre_reset
vfio_pci_get_pci_hot_reset_info
vfio_pci_host_match
vfio_pci_post_reset
This introduced a build failure on PPC when --without-default-devices
is use because VFIO is always selected in ppc/Kconfig but VFIO_PCI is
not.
Use an 'imply VFIO_PCI' in ppc/Kconfig and bypass compilation of the
VFIO EEH hooks routines defined in hw/ppc/spapr_pci_vfio.c with
CONFIG_VFIO_PCI.
