This commit introduces support for the Memory Protection Unit (MPU) to the ARM Cortex-R82 port. The MPU enhances system security by allowing the definition of memory regions with specific access permissions. The following changes have been made: - Added MPU configuration functions in `port.c` to set up memory regions and their attributes. - Updated `portASM.S` to include assembly routines for MPU and context switching with MPU support. - Created `mpu_wrappers_v2_asm.c` to provide assembly wrappers for MPU operations. - Updated `portmacro.h` to include MPU-related macros and definitions. - Modified `task.h` to include MPU-related task attributes. - Updated `CMakeLists.txt` to include the new MPU source file. - Enhanced the `README.md` with instructions on MPU configuration.

This commit includes minor code improvements to enhance readability and maintainability of the Cortex-R82 port files. Changes include refactoring variable names, optimizing comments, and improving code structure without altering functionality. Signed-off-by: Ahmed Ismail <Ahmed.Ismail@arm.com>
