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.

v2: use positive logic for including bits of NAND, rather than
a MINIMAL symbol that excludes things.
