[PATCH] nand: vf610_nfc: Do not abuse CONFIG namespace

[Tom Rini]

This driver uses the CONFIG namespace to set the chips internal CONFIG
namespace related bits.  However, CONFIG is reserved for the top-level
Kconfig based configuration system.  Use CFG as the namespace here
instead to avoid pollution.
