Use compute-cb@ subnodes instead of just cb@. Add qcom,glink-channels and qcom,smd-channels missing properties to make sure dtbs_check doesn't fail right off the bat. Correct the name of the parent node in the example from smd-edge to glink-edge. Since now the qcom,fastrpc bindings document is yaml, update the reference to it in qcom,glink-edge and also use $ref. Also update the MAINTAINERS file to point to the yaml version.
