[U-Boot] [PATCH V2 9/9] spl: nor: support loading i.MX container format file

[peng.fan at nxp.com]

From: Peng Fan <peng.fan at nxp.com>

i.MX8 only support AHAB secure boot with Container format image,
we could not use FIT to support secure boot, so introduce container
support to let SPL could load container images.
