From: Patrice Chotard <patrice.chot...@st.com>
For STM32F4 and F7 SoCx family, a specific stm32.h file exists.
Some common defines are duplicated or even unused in each of
these stm32.h.
Factorize all common definition in arch/arm/include/asm/stm32f.h and keep
specific definitions in each arch/arm/include/asm/arch-stm32fx/stm32.h.
