[PATCH v2 8/9] hw/core: Add qdev stub for user-mode

[Philippe Mathieu-Daudé]

While user-mode does not use peripherals (devices), it uses a
CPU which is a device.
In the next commit we will reduce the QAPI generated code for
user-mode. Since qdev.c calls qapi_event_send_device_deleted(),
let's add a stub for it.
