mtd: edit NAND-related comment (c478d7e4) · Commits · 戴 / test

This comment was unclear regarding which NAND functions do and do not support ECC on the spare area. This update should reflect the current status of the NAND system but can be updated if changes are made in the standard functions. Signed-off-by:
