stm32: Implement cache driver (C-M33 based series)

[erwango]

Is your enhancement proposal related to a problem? Please describe.
C-M33 based STM32 series (h5/l5/u5/wba) embed a cache peripheral.
To simplify STM32 generic driver implementation, provide a STM32 driver implementing zephyr cache API. It will allow call of sys_cache_ functions directly in STM32 drivers and commonalize this code with M7 based STM32.

Describe the solution you'd like
Implement a STM32 driver of zephyr cache API.

This is my first time to work with zephyr and I would like to work on drivers. It would be really helpful if someone can guide me about this issue with some more information and references. Tack :)

Hi, has there been much progress on this issue? If not, I would love to take a crack at it as my first issue. Any information on the current progress would be appreciated!
