[PATCH v3 10/10] [HACK] arm64: dts: renesas: ebisu: Enable LVDS dual-link operation

[Laurent Pinchart]

Enable and connect the second LVDS encoder to the second LVDS input of
the THC63LVD1024 for dual-link LVDS operation. This requires changing
the default settings of SW45 and SW47 to OFF and ON respectively.
