Subject: [PATCH] ARM: dts: stm32: Swap USART3 and UART8 alias on STM32MP15xx
 DHCOM SoM

BugLink: https://bugs.launchpad.net/bugs/2111953

[ Upstream commit 479b8227ffc433929ba49200182b6383569f9615 ]

Swap USART3 and UART8 aliases on STM32MP15xx DHCOM SoM,
make sure UART8 is listed first, USART3 second, because
the UART8 is labeled as UART2 on the SoM pinout, while
USART3 is labeled as UART3 on the SoM pinout.
