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

[ Upstream commit 73317d327123472cb70e9ecbe050310f1d235e93 ]

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.
