dt-binding: remoteproc: wcnss: Allow describing smd edge

Browse Source 
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.

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

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.
