[PATCH v5] arm64: dts: renesas: r9a07g043u11-smarc: Enable DU

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

Enable DU and link with the HDMI add-on board connected with
the parallel connector on RZ/G2UL SMARC EV by using Device
Tree overlay.

Signed-off-by: Biju Das <biju.das.jz@xxxxxxxxxxxxxx>
---
v4->v5:
 * Created Overlay for ADV 7513 transmiiter connected to DU
v3->v4:
 * Restored ports property in du node and port@0 for DPI interface.
v2->v3:
 * Replaced ports->port in du node as it support only DPI output.
v1->v2:
 * No change.
