The hardware denies any access from the Linux non-secure world to the secure-protected pins. Hence, prevent any driver to request such a pin.
Mark the secure-protected GPIO lines as invalid (.init_valid_mask) and prevent the pinmux request / pinconf setting operations. Identify the secure pins with "NO ACCESS" in the pinconf sysfs.
