mtd: nand: add more comment for MTD_NANDFLASH/MTD_MLCNANDFLASH

Browse Source 
In current code, the MTD_NANDFLASH is used to represent both the SLC and
MLC. It is confusing to us.

By adding an explicit comment about these two macros, this patch makes it
clear that:
	MTD_NANDFLASH    : stands for SLC NAND,
	MTD_MLCNANDFLASH : stands for MLC NAND (including TLC).
