Subject: [PATCH v3 3/3] ARM: dts: stm32: fix several DT warnings on stm32mp15
Several warnings regarding LTDC and DSI on stm32mp15* device-trees remains.
Those concern:
* "#size-cells" and "#address-cells" wrongly used
* residual "reg" property appearing on endpoints where it could be
avoided
* Changed 'panel-dsi@0' to 'panel@0' according to dsi-controller.yaml
