The device tree is based on the one in linux-stm32/stm32-next, which will probably be merged for Linux v5.8-rc1. Instead of waiting that long, we import it here with some stuff removed/changed, so it's usable for both barebox and Linux, without the prerequisite patches. The non-barebox specific parts have been moved into separate DTSIs (arch/arm/dts/stm32mp{157c-lxa-mc1,15xx-osd32}.dtsi), so both can be dropped after the v5.8-rc1 sync with only include path change necessary in arch/arm/dts/stm32mp157c-lxa-mc1.dts.
