rpmsg: Make rpmsg_create_ept() take channel_info struct
As we introduce support for additional rpmsg backends, some of these only supports point-to-point "links" represented by a name. By making rpmsg_create_ept() take a channel_info struct we allow for these backends to either be passed a source address, a destination address or a name identifier.
