Yes, that's the downside of this patch. Unfortunately we have the
situation that UBI attaches to mtd, so the cfi flash driver was broken
for cfi flashes. We used to add a fake mtd struct especially for UBI
on nor flashes, but the recently introduced ubiformat didn't cope with
that. This patch fixes this with the cost of increasing the binary size.
