5367b67be4 configs: stm32mp1: Add support for baudrates higher than 115200 for st-link
On STMicroelectronics boards, the UART can reliably go up to
2000000 bauds when connected to the on-board ST-LINK-V2 for STM32MP15

Unfortunately U-Boot will fall back to 115200 unless higher rates are
declared via CONFIG_SYS_BAUDRATE_TABLE.

This patch add the support of higher baudrates on STMicroelectronics
boards with ST-LINK.

806c4dd315 configs: stm32mp1: set the console variable for extlinux.conf
Set the environment variable "console", used in extlinux.conf file when it
is generated by YOCTO distribution with:

UBOOT_EXTLINUX_CONSOLE ??= "console=${console},${baudrate}"

With these 2 variables, U-Boot give dynamically the used console and
baudrate in the Linux kernel bootargs.

For the STMicroelectronics boards, the used console is ttySTM0.

c67ca25dfc board: stmp32mp1: split board and SOC STM32MP15 configuration
Add a configuration file "stm32mp15_st_common.h" to handle the
STMicroelectronics boards configuration and rename stm32mp1.h to
"stm32mp15_common.h" to handle the generic STM32MP15x series configuration.

The configuration file "dh_stm32mp1.h" is also renamed to
"stm32mp15_dh_dhcom" for the configuration of board based on the
dhelectronics STM32MP15x SOM.

In the STMicroelectronics board configuration the default bootcmd
"bootcmd_stm32mp" is updated to only select the extlinux file found on
SD-Card on STM32MP15x EV1 for boot from NOR device.
