STM32 serial IP can be reset via reset controller.
Add the support of reset to uart nodes on stm32mp15-u-boot.dtsi,
the ad-dons file for U-Boot.
This patch fix issues when previous UART configuration, for example
done in TF-A or ROM code, is not handled in U-Boot stm32 serial driver
init.
This reset property won't be not added in Linux kernel device tree
as this reset is not used in Linux STM32 serial driver.
