	On linux kernel side, on STM32F7 and STM32H7 SoCs, DMA requires uncachable regions. These regions are defined in DT. Since kernel linux v4.15, on ARMv7-M Cortex, kernel is able to configure MPU regions depending on DT settings. As kernel is able to configure MPU, this allows to remove MPU region settings in bootloader. On Cortex M processors, MPU allows to use a default memory map. (see B3.5.4 MPU Control Register, MPU_CTRL in https://developer.arm.com/products/architecture/m-profile/docs/ddi0403/latest/armv7-m-architecture-reference-manual) Use the default memory map as background region for all STM32 SoCs family with an additional MPU region corresponding to the SDRAM area.

	MPU's region setup can be factorized between STM32F4/F7/H7 SoCs family and used a common MPU's region config. Only one exception for STM32H7 which doesn't have device area located at 0xA000 0000. For STM32F4, configure_clocks() need to be moved from arch_cpu_init() to board_early_init_f(). Signed-off-by: Patrice Chotard <patrice.chotard@st.com> Reviewed-by: Vikas Manocha <vikas.manocha@st.com>
