accel/ivpu: Add bounds check for firmware runtime memory

accel/ivpu: Add bounds check for firmware runtime memory

Validate that the firmware runtime memory specified in the image
header is properly aligned and sized to hold the firmware image.
This prevents errors during memory allocation and image transfer.
