With the integration of the IAR toolchain support in TF-M it has become important to use the REGION_DECLARE/REGION_NAME macros in platform/region.h instead of using symbols like "Image$$ARM_LIB_STACK_MSP$$ZI$$Base".

The IAR linker can not use these symbols and the macros in combination with the IAR specific cmake rules creates appropriate symbols for all the supported toolchains.
