Arduino for STM32

Thanks @konczakp , PR is well formed
Anyway as stated in the PR, as it is a generic clock it should use internal clock source.

@fpiSTM It is also possible to use :

RCC_OscInitStruct.HSEState = RCC_HSE_BYPASS;

But with other changes that I've made. It seams that mainly PLLM, PLLN, PLLP, PLLQ, PLLR were wrong

As mentioned here: https://community.st.com/s/question/0D5 ... hsi-or-hse and here https://community.st.com/s/question/0D5 ... leo-boards It is better to use HSE which is more accurate for high speed transmissions and despite of temperature. This is why I choose HSE instead HSI

Best way to get this solved would be creating new Variant for Nucleo-STM32F413ZH (copy paste from generic) and set HSE as default and for the generic STM32 set BYPASS. What do You think?

Yes but as said as it is the generic clock it have to use HSI. Not all boards have an HSE. This is the goal of the generic.

Yes, all clock config need to be reviewed.

Exactly, creating a dedicated variant for a board is always the best solution to optimize it. That's why I suggest in the issue I've opened to add it.
