Subject: [PATCH v6 3/3] arm64: dts: renesas: Add LVDS decoder to R-Car V3M Eagle

The R-Car V3M Eagle board includes a transparent THC63LVD1024 LVDS
decoder, connected to the on-chip LVDS encoder output on one side
and to HDMI encoder ADV7511w on the other one.

As the decoder does not need any configuration it has been so-far
omitted from DTS. Now that a driver is available, describe it in DT
as well.
