ARM: stm32mp: add board support for STM32MP135F-DK
We already have the needed drivers in place to support the upcoming
STM32MP131. Linux already has a basic DT for the DK board. Add a barebox
board that leverages it. To try it out modify the existing FIP with:
fiptool update --nt-fw build/images/barebox-stm32mp-generic-bl33.img \
--hw-config build/arch/arm/dts/stm32mp135f-dk.dtb \
mmcblk0p3
