[RFC 18/21] arm64: dts: salvator-x: Add DU pins, HDMI connectors and encoder

[Ulrich Hecht <ulrich.hecht+renesas@xxxxxxxxx>]

From: Koji Matsuoka <koji.matsuoka.xm@xxxxxxxxxxx>

Based on work by Koji Matsuoka.

Signed-off-by: Ulrich Hecht <ulrich.hecht+renesas@xxxxxxxxx>
[geert: Re-add removed extal_clk]
[geert: Modify existing du node instead of moving it around]
[geert: Use generic pinctrl properties]
