[U-Boot] [PATCH 5/6] imx8: Add support to get container image set size

To avoid hardcoded offset when adding u-boot.cnt to flash.bin, we use
flexible offset which is calculated based on the size of the container
image generated int the first stage. And pad u-boot.cnt at 1KB
alignment.
So add code to get the offset when SPL loading u-boot.cnt.
