dt-binding: remoteproc: wcnss: Allow describing smd edge
Allow the associated smd edge to be described within the wcnss
remoteproc node. This creates a bond between the remoteproc and the
associated smd channels and devices, showing the interaction between the
two parts and provides both a natural reference to the other.
