rpmsg: glink: Introduce glink smem based transport
The glink protocol supports different types of transports (shared memory). With the core protocol remaining the same, the way the transport's memory is probed and accessed is different. So add support for glink's smem based transports. Adding a new smem transport register function and the fifo accessors for the same.
