ARM: stm32: prepare stm32 family to welcome armv7 architecture

Browse Source 
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 for most of
them. If a hardware block is specific to one family we can use either
ARM_SINGLE_ARMV7M or ARCH_MULTI_V7 flag.

Introduction
------------
The STMicroelectronics family of Cortex-M based MCUs are supported by the
'STM32' platform of ARM Linux. Currently only the STM32F429 (Cortex-M4)
and STM32F746 (Cortex-M7) are supported.
The STMicroelectronics STM32 family of Cortex-A microprocessors (MPUs) and
Cortex-M microcontrollers (MCUs) are supported by the 'STM32' platform of
ARM Linux.
Configuration
-------------
A generic configuration is provided for STM32 family, and can be used as the
default by
For MCUs, use the provided default configuration:
make stm32_defconfig
For MPUs, use multi_v7 configuration:
make multi_v7_defconfig
