MLK-12500-1 HAB: Add kernel image authentication in image loading
To support the trust boot chain, we integrate the authentication
into the kernel image loading process. The kernel image will be verified
at its load address. So when signing the kernel image, we need to
use this load address which may change on different platforms.
