[PATCH/RFT] arm64: dts: renesas: r8a77990: Add cpg reset for LVDS Interface

[Yoshihiro Kaneko]

From: Takeshi Kihara <takeshi.kihara.df@renesas.com>

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.

This patch is based on the devel branch of Simon Horman's renesas tree.
