[U-Boot] [PATCH 7/9] spl: Restart loading if load_image returns -EAGAIN

[Marek Vasut]

If the loader->load_image returns -EAGAIN, it is an indication
the loading process should restart the loading, possible due to
DTO being applied on the U-Boot's DT. Restart the loading until
the loader stops returning -EAGAIN.
