2536f18bfa arch-stm32: Factorize stm32.h for STM32F4 and F7
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.

c5c1756c68 mtd: stm32: use parameter instead of default value
To set wait state, a hard coded value is used instead of using
latency parameter. stm32_flash_latency_cfg() is currently used
in arch/arm/mach-stm32/stm32f4/clock.c and in
drivers/clk/clk_stm32f7.c with, in both case, "5" as parameter.

9082517a85 stm32: stm32_flash: add memory barrier during flash write
After writing data to flash space, next instruction is checking if flash
controller is busy writing to the flash memory. Memory barrier is required here
to avoid transaction re-ordering for data write and busy status check.

9ecb0c416c stm32: stm32f4: move flash driver to mtd driver location
Same flash driver can be used by other stm32 families like stm32f7.
Better place for this driver would be mtd driver location.
