[RFC PATCH 5/5] ARM: dts: stm32: Add Octavo OSD32MP1-RED board

[Sean Nyekjaer <sean@xxxxxxxxxx>]

Add support for the Octavo OSD32MP1-RED development board.

General features:
 - STM32MP157C
 - 512MB DDR3
 - CAN-FD
 - HDMI
 - USB-C OTG
 - UART

This is made with great inspiration from Neeraj Dantu's work:
https://raw.githubusercontent.com/octavosystems/OSD32MP1-RED-Device-tree/main/linux-v5.10-r0/stm32mp157c-osd32mp1-red.dts

So what copyright is needed here?
And author?

Still need to test ethernet and HDMI, thats why I have done this a RFC.
