[PULL 13/32] hw/vfio: Have VFIO_PLATFORM devices inherit from DYNAMIC_SYS_BUS_DEVICE

[Philippe Mathieu-Daudé]

Do not explain why VFIO_PLATFORM devices are user_creatable,
have them inherit TYPE_DYNAMIC_SYS_BUS_DEVICE, to make explicit
that they can optionally be plugged on TYPE_PLATFORM_BUS_DEVICE.
