[PATCH v2 09/13] arm64: dts: st: add ltdc support on stm32mp251

[Raphael Gallais-Pou <raphael.gallais-pou@foss.st.com>]

The LCD-TFT Display Controller (LTDC) handles display composition,
scaling and rotation.  It provides a parallel digital RGB flow to be
used by display interfaces.

Add the LTDC node.
