Subject: [PATCH] base-files: read iopsys,rootfs-data-alignment from FIT image
Replaced the hardcoded rootfs data alignment value with dynamic retrieval
from the FIT image using the iopsys,rootfs-data-alignment property.
This ensures that the alignment is consistent with the value embedded
during image generation and improves flexibility across different devices.
Issue: #16567
