dt-bindings: remoteproc: qcom,glink-edge: require channels in children

GLINK edge contains subnodes representing devices related to the remote
processor.  Each of such device (e.g. APR or FastRPC) must have
a "qcom,glink-channels" property.  However the APR or FastRPC device can
be also part of other communication - SMD - thus their schema does not
require "qcom,glink-channels".

To make the GLINK edge bindings strict, require "qcom,glink-channels"
for its children.
