Subject: [PATCH] mtd: cfi_cmdset_0001: 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.
This is similar fix to: 557c759036fc3976a5358cef23e65a263853b93f.
