1. add cpuname config for the rpmsg virtio devices, so the rpmsg virtio driver can get the local and remote cpuname from the virtio config space, and we can distinguish the differnt channel when there are two rpmsg virtio devices in the same resource table; 2. optimize the remoteproc virtio transport layer to make it can work with all the virtio devices instead only work with rpmsg virtio devices; Signed-off-by: Bowen Wang <wangbowen6@xiaomi.com>
