When using the LPC55S69 with TF-M, the ROM-based flash controller is restricted to the secure processing environment to prevent NS access to flash memory. Any access to the flash controller will cause a secure fault, and the NS application will halt execution. This commit disables access to the IAP flash peripheral when using the lpcxpresso55s69_ns target, enabling TF-M to restrict IAP access to the secure side.
