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.

= SUBNODES

A single subnode of the WCNSS PIL describes the attached rf module and its

resource dependencies.

A required subnode of the WCNSS PIL is used to describe the attached rf module

and its resource dependencies. It is described by the following properties:

The wcnss node can also have an subnode named "smd-edge" that describes the SMD

edge, channels and devices related to the WCNSS.

See ../soc/qcom/qcom,smd.txt for details on how to describe the SMD edge.



= EXAMPLE

The following example describes the resources needed to boot control the WCNSS,

with attached WCN3680, as it is commonly found on MSM8974 boards.
