Use linker script variables for MPU setup for Nuvoton M2351 Keil Project
Earlier we were using hard-coded addresses for MPU setup which were ensured to be the same as linker script setup. This change updates the Keil uVision project for Nuvoton Numaker-PFM-M2351 to use the variables exported from the linker script. This ensures that the MPU setup never goes out of sync with linker script.
