Enable MPU and CPU cache for Corstone-300
- Enable CPU instruction- and data cache by default.
- Add a CMake option to turn CPU cache on/off.
- Add basic MPU configuration for memory areas. Make the code
segment RO (NS address' are reachable from secure state,
hence MPU config entries for both S and NS address of ITCM).
- Target latest NPU API version
