[U-Boot] [RFC PATCH 12/17] spl/nand: config symbol documentation

[Scott Wood]

Document parameters used for specifying the NAND image to be loaded.

Also fix the definition of CONFIG_SPL_NAND_SIMPLE -- it's only
nand_spl_simple.c, not the entire nand directory.  The word "simple" is
there for a reason.  :-)
