Add #interconnect-cells on main &noc so that it will probe the platform
interconnect providers. Other devices can request icc_paths like this:
interconnects = <&noc BUS_MASTER_ID &noc BUS_SLAVE_ID>
And interconnect-node-id properties on &noc and &ddrc, the interconnect
provider will scan these and make PM QoS frequency requests in response
to bandwith request from other drivers.
