mtd: nand: add more comment for MTD_NANDFLASH/MTD_MLCNANDFLASH
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).
