Subject: [PATCH v4 2/4] arm64: dts: renesas: r8a779a0: Add DSI encoders

Provide the two MIPI DSI encoders on the V3U and connect them to the DU
accordingly.

Reviewed-by: Laurent Pinchart <laurent.pinchart@...asonboard.com>
Signed-off-by: Kieran Bingham <kieran.bingham+renesas@...asonboard.com>
---
v2
 - Fixup indentation

v3
 - Fix the clock references
 - Fixup dsi1 as well

-v4:
 - Use the correct pll clocks.


This is still pending approval/integration of the DSI encoder bindings
