[PATCH-for-10.0 0/8] hw/boards: Remove legacy MachineClass::pci_allow_0_address flag

[Philippe Mathieu-Daudé]

This series aims to remove a legacy field from
MachineClass.

Rather than a global exposed to all machines,
use a pci-bus specific flag on each machine
requiering it.

IMO it would be cleaner to add the property
at the PCI_BUS level, but we only provide qdev
properties for *devices*, not *buses*. Meanwhile
we could register the property using plain QOM
API, but at this stage I thought it might be
over-engineering, so I restricted to property
to the GPEX device. After all, there is no
concern by similar PCI_BUS_EXTENDED_CONFIG_SPACE
use.

  hw/pci/pci_bus: Introduce PCIBusFlags::PCI_BUS_IO_ADDR0_ALLOWED
  hw/ppc/spapr_pci: Set PCI_BUS_IO_ADDR0_ALLOWED flag in host bridge

  hw/arm/virt: Set PCI_BUS_IO_ADDR0_ALLOWED flag on GPEX host bridge
  hw/arm/sbsa-ref: Set PCI_BUS_IO_ADDR0_ALLOWED flag on GPEX host bridge
  hw/riscv/virt: Remove pointless GPEX_HOST() cast
  hw/riscv/virt: Set PCI_BUS_IO_ADDR0_ALLOWED flag on GPEX host bridge
  hw/pci/pci: Remove legacy MachineClass::pci_allow_0_address flag
