Therefore, this patch adds CPG reset properties in DU device node for the R8A77990 SoC. According to Laurent Pinchart, R-Car Gen3 reset is handled at the group level so specifying one reset entry per group is sufficient. For this reason <&cpg 724> is not listed as a reset for "du.1" as was the case in an earlier revision of this patch.
