hw/pci: add QEMU-specific PCI capability to the Generic PCI Express Root Port
To enable hotplugging of a newly created pcie-pci-bridge, we need to tell firmware (e.g. SeaBIOS) to reserve additional buses or IO/MEM/PREF space for pcie-root-port. Additional bus reservation allows us to hotplug pcie-pci-bridge into this root port. The number of buses and IO/MEM/PREF space to reserve are provided to the device via a corresponding property, and to the firmware via new PCI capability. The properties' default values are -1 to keep default behavior unchanged.
