[PATCH v2 5/6] arm64: dts: renesas: r8a77990: ebisu: Enable LVDS1 encoder

[Laurent Pinchart]

The LVDS1 encoder must supply a pixel clock to the DU for the DPAD
output when the LVDS0 encoder is used. Enable it despite its output not
being connected.

Changes since v1:

- Add a comment in the DT to explain why the LVDS1 encoder needs to be
  enabled.
