The capabilities have default values which doesn't reflect the reality
when it concerns the base clock and the mul value. Use a fixe rate

MPU's region setup can be factorized between STM32F4/F7/H7 SoCs family
and used a common MPU's region config.

Only one exception for STM32H7 which doesn't have device area
located at 0xA000 0000.

For STM32F4, configure_clocks() need to be moved from arch_cpu_init()

STM32F4 uses a different RCC variant than STM32F7. For STM32F4

Like STM32H7, now STM32F4/F7 clock drivers are binded by

This also allows to add reset support to STM32F4/F7 SoCs family.
