dt-bindings: remoteproc: qcom,smd-edge: define children

SMD edge contains subnodes representing devices related to the remote
processor. With limietd number of remote processors, there is a limited
set of such devices.

List all of them in smd-edge bindings so schema can strictly check for
subnodes.

Additional benefit is requirement of "qcom,smd-channels" for such
subnodes, because their schema cannot enforce it (few devices like APR
or FastRPC can be part of either SMD or GLINK edge).
