[PATCH v6 19/25] spl: Convert net to spl_load

[Sean Anderson]

This converts the net load method to use spl_load. As a result, it also
adds support for LOAD_FIT_FULL and IMX images.

Signed-off-by: Sean Anderson <seanga2 at gmail.com>

Changes in v6:
- Explicitly initialize load_info members

Changes in v5:
- Rework to load header in spl_load
