    boards/nrf53: fix BLE HCI initialization for app core
    
    After simplifications in NuttX init process, app core boots too fast so that
    net core doesn't have time to initialize HCI service.
    
    Let's add a short sleep before BLE initialization in app core as a temporary
    fix, in the future it should be done better.
