Implement `setup_mm` for MPU systems. This variant does not require setting up a direct map.
To reduce code duplication the common initalisation code for both MPU and MMU Arm64 configurations is refactored into `setup_mm`. Platform-specific setup steps are now handled by a new helper function `setup_mm_helper`.
