[PATCH] MTD_NAND_SHARPSL and MTD_NAND_NANDSIM should be tristate's

MTD_NAND=m and MTD_NAND_SHARPSL=y or MTD_NAND_NANDSIM=y are illegal
combinations that mustn't be allowed.

This patch fixes this bug by making MTD_NAND_SHARPSL and MTD_NAND_NANDSIM
tristate's.

Additionally, it fixes some whitespace damage at these options.
