arm: mpu: clear mpu regions before initialization Disabling the MPU doesn't clear regions configuration. There is a risk in multi-image environment that there are some old region setting e.g. stack guard. This may cause a memory fault, because of different images layout e.g. RO/RW. Just clear and disable all regions configuration before the new initialization. Signed-off-by: Dawid Niedzwiecki <dawidn@google.com>
