[U-Boot] [U-Boot, v1, 1/4] spl: record boot_device into spl_image and call spl_perform_fixups

[Philipp Tomsich]

>  - we provide an extension-point for boards/architectures that can
>    perform late fixups depending on a fully populated spl_image
>    structure (i.e. we'll know the final boot_device and have info
>    on the image type and operating system to be booted).
