rpmsg: Make rpmsg_{register|unregister}_device() public

Make function rpmsg_register_device() and rpmsg_unregister_device()
functions public so that they can be used by other clients.  While
doing so get rid of two obsolete function, i.e register_rpmsg_device()
and unregister_rpmsg_device(), to prevent confusion.
