Subject: [PATCH 0/3] arm64: dts: st: add usart nodes for stm32mp25

STM32MP25 got the same serial hardware block as STM32MP1x but with two improvements:
 - TX and RX FIFO have been extended to 64 bytes.
 - one instance more than in STM32MP1x series (4x usart and 5x uart).
 
STM32MP257F-EV1 board has one usart used by console and one usart on IO port.
