[PATCH v6 21/25] spl: Convert NVMe to spl_load

[Sean Anderson <seanga2@gmail.com>]

This converts the blk load method (used exclusively by NVMe) to use
spl_load. As a consequence, it also adds support for LOAD_FIT_FULL and
IMX images.

Changes in v6:
- Fix invalid return from spl_blk_load_image
- Explicitly initialize load_info members

Changes in v5:
- New
