NAND: Part 2: Fix warning Please define CONFIG_SYS_64BIT_VSPRINTF...

Commit 8d2effea added a warning for configurations that use NAND
without defining the (then necessary) CONFIG_SYS_64BIT_VSPRINTF but
failed to fix the affected boards.

This patch covers the non-PPC boards that were missed in the previous
patch (commit 170c1972).
