Add demos / board support for MCUDev DevEBox STM32H7XX_M (STM32H743VIT6)

[harwHarw03]

#Hi,
It would be great to have proper board support and demos for the MCUDev DevEBox STM32H7XX_M (STM32H743VIT6)

board reference: https://stm32-base.org/boards/STM32H743VIT6-STM32H7XX-M.html

Tried running the NUCLEO-H743ZI demo (RT-STM32H743ZI_REV_XY-NUCLEO144) with some modification on mcuconfig and board files (following PlayEmbedded tutorials and forum threads), but the board still doesn’t run the demo.

Is the STM32H7 port confirmed to be working on current ChibiOS?
If yes, having proper board files or a small demo for this DevEBox would help a lot.
Thanks!
