[PATCH v4 0/4] STM32 warning cleanup

[Raphael Gallais-Pou]

This serie aims to reduce the number of device-tree warnings of
following boards :

  - STM32F469-DISCO
  - STM32MP15*

Those warnings were appearing either during build or when checking
dt-bindings and concern mostly LTDC and DSI IPs. They were due to the
following cases:

  - 'panel-dsi at 0' instead of 'panel at 0' according to the YAML
  - unnecessary #address-cells and #size-cells properties
  - residual 'reg' field on single endpoints

First patch fixes stm32f469-disco device-tree.
Second patch fixes st,stm32-dsi.yaml dt-bindings.
Third patch fixes DSI warnings on stm32mp15* device-trees.
Last patch fixes LTDC warnings on stm32mp15* device-trees.

Changes since v3:
	* Added Conor's acked-by
	* Added Marek's reviewed-by
	* Split last patch into two separate for clearer review

Changes since v2:
	* Added changelog
	* Enhanced commit descriptions

Changes since v1:
	* Added DSI subnode name change
	* Included stm32f469-disco DT in the cleanup
	* Included YAML fix to prevent regression
