    Since commit 4dffed5b ("rpmsg: Name rpmsg devices based on
    channel id"), it is no more possible for a firmware to register twice
    a service (on different endpoints). rpmsg_register_device function
    is failing when calling device_add for the second time as second
    device has the same name as first one already register.
    It is because name is based only on service name and so is not more
    unique. Previously name was unique thanks to the use of rpmsg_dev_index.
    
    This patch adds destination and source endpoint numbers device name to
    create an unique identifier.
    
    Fixes: 4dffed5b ("rpmsg: Name rpmsg devices based on channel id")
