STM32 WBA series USB support

[yossilevy54321]

Last month the support of nucleo_wba65ri (#88407 PR) was added on main.
It seems though both dts and driver files (usb_dc_stm32.c for example) do not support USB for the board\wba-series.
Is it planned or currently in-the-making supporting this?

Yes, PLEASE. I have two wba65 devkits sitting on my desk, which I can't use to run USB CDC ACM applications on :-(

To whom it may concern: this is how far I got with the RM515 document and copy & paste from STM32H745 code. Build fails with compilation error in usb_dc_stm32.c.
