[feature] Support for STM32U5-series

[Nightwalker-87]

Currently the U5 family is not supported.

• [x] Programmer/board type: STlink/v2, STlink/v2-onboard, STlink/v3
• [x] Operating system: Linux, Mac OS X, Windows (with specific version)
• [x] Stlink tools version and/or git commit hash: v1.6.1
• [x] Stlink commandline tool name: st-info, st-flash, st-util
• [x] Target chip (and optional board): STM32U5-series

what does this mean ? I'm not aware of such thing !

The only real issue is that the WL55 and H7 have the same core_id

There were unintended leftovers from another ticket which served as a template by mistake. I've removed it. Thanks for the note. The U5 series has been announced by ST recently: https://www.st.com/en/microcontrollers-microprocessors/stm32u5-series.html

indeed, I already added support of this device in OpenOCD http://openocd.zylin.com/#/c/6108/ the flash delta's are in the commit msg ...

flash/stm32l4x: add support of STM32U57x/U58x

this device flash registers are quite similar to STM32L5 with this changes :

• flash size is up to 2MB
• 2MB variants are always dual bank
• 1MB and 512KB variants could be dual bank (contiguous addressing) depending on DUALBANK bit(21)
• flash data width is 16 bytes (quad-word)

Related to #1005.

A first contribution to this topic is a (preliminary) chip-id file for the STM32U5 series in branch chipid_cleanup.

Hi, is there any update on this? The device seems to be still unsupported..

@tarek-bochkati: The .chip config-file for the STM32U5 series, holding all device-specific configuration, is now complete. It will be pushed to our nightly branch very soon to allow for a review. We also seem to have most of the library functions for handling this device type. Many of them appear to be equal or similar to the STM32L5 series. However we now need additional know-how and contribution to address this issue...

We need people to test the changes and relevant features.

Hello everybody. Getting in touch with staff on the ST-Microelectronics booth at the Embedded World 2023 resulted in a Nucleo STM32U575ZI-Q board as a give-away. :tada: Of course one of the first subsequent ideas was to proceed here, now being able to do some testing myself. I managed to get the board working with the toolset after fixing a wrong setting in the related chip-id file. Finally here is the result I get:

So maybe there will also be some progress at #1005 soon, as both MCU families do share some settings.
