It is necessary to reset the LVDS Interface according to display on/off.
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.
