[PATCH] ARM: dts: stm32: Deduplicate serial aliases and chosen node for STM32MP15xx DHCOM SoM

[Christoph Niedermaier]

> From: Marek Vasut <marex at denx.de>
> Sent: Wednesday, November 6, 2024 12:30 AM
> Deduplicate /aliases { serialN = ... } and /chosen node into
> stm32mp15xx-dhcom-som.dtsi , since the content is identical
> on all carrier boards using the STM32MP15xx DHCOM SoM. No
> functional change.
