So instead of using the imx_icc_node_adj_desc, we use the fsl,icc-id property that is in each NoC (or pl301) to the icc node (based on the id) to it. Along with all the NoC and pl301 nodes in the dts we will have a interconnect dedicated node. This node will be the actual device of the icc provider.
