To connect STM32H7 that is in SLEEPD1 state (e.g. during REPL)debuggers like st-flash or openocd must assert SRST.Signed-off-by: Oliver Joos <oliver.joos@hispeed.ch>
e485a45 to373cab9CompareSTM32CubeMX shows a conflict of UART5 with ETH MII.However UART1 can be used with TX and RX on the pin headers.PLL1Q is reduced from 200 to 100 MHz because it may be used for FDCANor SDMMC. FDCAN needs <= 150 MHz, and 100 MHz is enough for an SDCardconnected to pin headers to work reliably.Signed-off-by: Oliver Joos <oliver.joos@hispeed.ch>

I have added support for MCU
STM32H753xxand its ST NUCLEO-H753 board.Most configuration files rely on the corresponding files of NUCLEO_H743ZI2 and its predecessor NUCLEO_H743ZI (now obsolete).
I tested the 3 LEDs, the USER switch, Ethernet, the REPL on ST-Link UART and on the second USB port as well as storage with USB MSC access.
The image of my NUCLEO_H753ZI is here:micropython/micropython-media#108 .
