[PATCH v4 2/7] ARM: stm32: prepare stm32 family to welcome armv7 architecture

From: Ludovic Barre This patch prepares the STM32 machine for the integration of Cortex-A based microprocessor (MPU), on top of the existing Cortex-M microcontroller family (MCU). Since both MCUs and MPUs are sharing common hardware blocks we can keep using ARCH_STM32 flag
