CONFIG_NAND_U_BOOT indicates that there is a NAND SPL involved, and is
set in both build stages.

CONFIG_NAND_SPL is set only when building the SPL code itself.

When Haiying said "used as CONFIG_NAND_...", I believe she meant that
the difference between these two symbols is analagous to the difference
between the two NAND symbols -- not that they can be used
interchangeably.

I think the names need to be differentiated by more than just "_SYS",
though.
