Is your feature request related to a problem?

The STM32 HAL drivers sources are directly copied in sub-directories in radio/src/thirdparty/.
This makes the evolution of changes complex and does not allow a direct link with the STMicroelectronics github repositories.

Describe the solution you'd like

This proposed change consist to replace STM32 HAL drivers directories (radio/src/thirdparty/STM32F2xx_HAL_Driver, radio/src/thirdparty/STM32F4xx_HAL_Driver, radio/src/thirdparty/STM32H7xx_HAL_Driver & radio/src/thirdparty/STM32H7RS_HAL_Driver), by the next repositories included as submodules:

• https://github.com/STMicroelectronics/stm32f2xx-hal-driver
• https://github.com/STMicroelectronics/stm32f4xx-hal-driver
• https://github.com/STMicroelectronics/stm32h7xx-hal-driver
• https://github.com/STMicroelectronics/stm32h7rsxx-hal-driver

Describe alternatives you've considered

No response

Additional context

I perform a diff between the STM32 HAL drivers sources and STMicroelectronics github repositories, to evaluate the risk to implement this change.
Only minor changes observed on stm32f4 drivers. No change observed for the other ones.
In my opinion, these no risk to implement this change.
