d1c07785fd 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.

9f779fa410 imx8: disable node when the resource is not owned
When resource is not assigned to non-secure Linux, if linux continue
to use the node, linux may crash or hang. So need to set the node
status to disabled for not owned resources.

The resource id is in the power-domains property in device tree,
so parse the power-domains property to get the resource id and
use scfw api to check whether it is owned by current partition.
