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.

Filename to read to load U-Boot when reading from FAT
CONFIG_SPL_NAND_BASE
Include nand_base.c in the SPL. Requires
CONFIG_SPL_NAND_DRIVERS.
CONFIG_SPL_NAND_DRIVERS
SPL uses normal NAND drivers, not minimal drivers.
CONFIG_SPL_NAND_ECC
Include standard software ECC in the SPL
