Generate DCMI pins definitions for H7 family.

Looks good to me but would it be possible to generate pins as well for other series?
I know driver is H7 specific for now (at least only validated on H7), but support might be extended in future. Having pins already available would be a good start.
This is the way we're proceeding in general.

Hi, @erwango.

I have two questions about the files generated after run the Python script:

1. Do I have to add also the new dtsi files related to STM32H523, STM32H533, STM32H7R, and STM32H7s families? Those files are totally new.
2. I noticed that in stm32h725iekx-pinctrl.dtsi, stm32h725igkx-pinctrl.dtsi, stm32h730ibkxq-pinctrl.dtsi, and stm32h735igkx-pinctrl.dtsi files, the adc3_inp16_ph5 was removed. Do I have to accept this modification? I'll check if something similar happens with other files.

Thanks for raising this @CharlesDias.
This probably comes from the fact that you're generating from a latest version of open_pin_data repo.
2 options:

• Keep working with this commit, but then do it in 2 passes: first new batch from the new version w/o dcmi files, then add the new pinctrl, generate once again and provide the new signals in a 3 commit. In this case, don't forget to update commit used in https://github.com/zephyrproject-rtos/hal_stm32/blob/main/dts/README.rst (or maybe it is done automatically)
• Generate from SHA1 version provided in https://github.com/zephyrproject-rtos/hal_stm32/blob/main/dts/README.rst. And let the open_pin_data update aside for now.

Hi, @erwango.

I choose the second option. ;-)

This is fine for me now, but please update the first commit title to remove H7 reference, as pr is stm32 generic now.

Ping @CharlesDias.
I'm queuing #210
