spl: Support loading a FIT from NAND
Detect a FIT when loading from NAND and handle it using the new FIT SPL support. Reviewed-by: Tom Rini <trini@konsulko.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com> [trini: Make sure we continue to use (void *)(unsigned long) for load_addr]. Signed-off-by: Tom Rini <trini@konsulko.com>
