mtd: cfi_cmdset_0002: Disable write buffer functions if FORCE_WORD_WRITE is 1
Some write buffer functions are not used when FORCE_WORD_WRITE is set to 1.
So the compile warning messages are output if FORCE_WORD_WRITE is 1. To
resolve this disable the write buffer functions if FORCE_WORD_WRITE is 1.
