Move the helper file arm_mpu_mem_cfg.h, which translates the values of the Kconfig symbols CONFIG_FLASH_SIZE and CONFIG_SRAM_SIZE to size definitions to be used during MPU setup, from a Cortex-M-specific include directory to the Cortex-agnostic zephyr/arch/arm/mpu directory, as: - the contents of this header file are not dependent on the target being an ARMv7M, only ARMv8M is excluded, but the contents are identical for the ARMv7/8 Cortex-R MPU implementation, - the header file zephyr/arch/arm/mpu/arm_mpu.h, included within arm_mpu_mem_cfg.h, is also compatible with both Cortex-M and Cortex-R, the distinction between the two implementations takes place at an even lower level, - several ARMv7/8 Cortex-R targets now reference this header file in their MPU region setup (Xilinx ZynqMP, TI K3, Renode cortex_r8_virtual) while so far referencing it in an ARMv7 Cortex-M-specific include directory.
