spl/nand: introduce CONFIG_SPL_NAND_DRIVERS, _BASE, and _ECC.
Some small SPLs do not use nand_base.c, and a subset of those also require a special driver. Some SPLs need software ECC but others can't fit it. All existing boards that specify CONFIG_SPL_NAND_SUPPORT have these symbols added to preserve existing behavior. Signed-off-by: Scott Wood <scottwood@freescale.com> -- v2: use positive logic for including bits of NAND, rather than a MINIMAL symbol that excludes things.
