[U-Boot] [PATCH v2 3/5] arch-stm32: Factorize stm32.h for STM32F4 and F7

From: Patrice Chotard <patrice.chotard at 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.
Signed-off-by: Patrice Chotard <patrice.chotard at st.com>

v2: _ create arch/arm/include/asm/arch-stm32 directory and move
stm32f.h in it.
