Add new STM32 MCU boards and Documentation
STM32 programmer improvements
video: support several LTDC HW versions and fix data enable polarity
board: fix stboard error message, consider USB cable connected when boot device is USB
configs: stm32mp1: set console variable for extlinux.conf
configs: stm32mp1: add support for baudrate higher than 115200 for ST-Link
ARM: stm32mp: Fix Silicon version handling and ft_system_setup()
phy: stm32-usbphyc: Add DT phy tuning support
arm: dts: stm32mp15: alignment with v5.18
ram: Conditionally enable ASR
mach-stm32mp: psci: retain MCUDIVR, PLL3CR, PLL4CR, MSSCKSELR across suspend
configs: Use TFTP_TSIZE on DHSOM and STMicroelectronics boards
ARM: stm32: Use default CONFIG_TFTP_BLOCKSIZE on DHSOM
pinctrl: stm32: rework GPIO holes management
