[PATCH v4 0/7] Resolve TYPE_PIIX3_XEN_DEVICE |

There is currently a dedicated PIIX3 device model for use under Xen. By reusing
existing PCI API during initialization this device model can be eliminated and
the plain PIIX3 device model can be used instead.
Resolving TYPE_PIIX3_XEN_DEVICE results in less code while also making Xen
agnostic towards the precise south bridge being used in the PC machine. The
latter might become particularily interesting once PIIX4 becomes usable in the
PC machine, avoiding the "Frankenstein" use of PIIX4_ACPI in PIIX3.
Testing done:
- `make check`
- Run `xl create` with the following config:
name = "Manjaro"
type = 'hvm'
memory = 1536
apic = 1
usb = 1
disk = [ "file:manjaro-kde-21.2.6-220416-linux515.iso,hdc:cdrom,r" ]
device_model_override = "/usr/bin/qemu-system-x86_64"
vga = "stdvga"
sdl = 1
- `qemu-system-x86_64 -M pc -m 2G -cpu host -accel kvm \
-cdrom manjaro-kde-21.2.6-220416-linux515.iso`
v4:
- Add patch fixing latent memory leak in pci_bus_irqs() (Anthony)
v3:
- Rebase onto master
v2:
- xen_piix3_set_irq() is already generic. Just rename it. (Chuck)
