This patch implements a service that adds multiple instances capabilities to RPMsg. Each instance is allocated a separate piece of shared memory. Multiple instances provide independent message processing. Each instance has its own work_q. Signed-off-by: Marcin Jeliński <marcin.jelinski@nordicsemi.no>
