[fix] nucleo-h7431 updated user led pin and name

[jankoerner]

According to section 7.6.1 LEDs of the NUCLEO-H743ZI user manual is no blue user led.

Instead the board has a yellow user led connected to PE1.

Lol, you're correct, but ST has made this unnecessarily complex. What I have lying around is NUCLEO-H743ZI (MB1137), but what you likely have is NUCLEO-H743ZI2 (MB1364), which seems to be a different board layout?

I would recommend to add a new board definition called :board:nucleo-h743zi2 and use a Jinja2 template switch in the :board:nucleo-h743zi header file to service both. Example for the Black Pill F4 Boards.

Thanks for your feedback!
I have a NUCLEO-H753ZI board which adds the Cryptography feature to the NUCLEO-H743ZI2 but is besides from that similar to the NUCLEO-H743ZI2 board.

Would you recommend to add an additional board definition :board:nucleo-h753zi for this board as well?

[salkinium]

Yes absolutely, also with the jinja2 template trick if it's super similar like this.

What MB number is on your board?

[jankoerner]

Okay, I think it is MB1364.
But I need to check again on Monday.
