arm64: dts: renesas: r8a77995: draak: Enable HDMI display output

Adds LVDS decoder, HDMI encoder and connector for the Draak board.

The LVDS0 and LVDS1 encoders can use the DU_DOTCLKIN0, DU_DOTCLKIN1 and
EXTAL externals clocks. Two of them are provided to the SoC on the Draak
board, hook them up in DT.
