[PULL 05/23] hw/pci-host/raven: Simplify creating PCI facing part

Posted by Philippe Mathieu-Daudé 2 weeks, 3 days ago

From: BALATON Zoltan <balaton@eik.bme.hu>

There is no need to init and realize the PCI facing part of the host
bridge separately as it does not expose any properties that need to be
available before realize. It can be simpilfied using pci_create_simple.
