Add a SPL test for the NAND load method. We use some different functions to do the writing from the main test since things like nand_write_skip_bad aren't available in SPL.
We disable BBT scanning, since scan_bbt is only populated when not in SPL. We use nand_spl_loaders.c as it seems to be common to at least a few boards already. However, we do not use nand_spl_simple.c because it would require us to implement cmd_ctrl. The various nand load functions are adapted from omap_gpmc. However, they have been modified for simplicity/correctness.
