[Qemu-devel] [RFC PATCH 04/14] spapr_pci: Fold spapr_phb_vfio_eeh_configure() into spapr_pci code

[David Gibson]

Because spapr_phb_check_vfio_group() now safely returns an error on a non
VFIO papr host bridge, it becomes safe to call
spapr_phb_vfio_eeh_configure() on any host bridge, not just the special
VFIO host bridges.

So fold its code into rtas_ibm_configure_pe(), instead of only calling it
via a class method.
