[MTD] CHIPS: Recognize Spansion CFI 1.4 chips
Modify Amd/Fujitsu CFI NOR flash primary vendor extension table revision check to recognize version 1.4. Verified the existing driver can handle version 1.4 chips without additional info from 1.4 extended table. Move the primary vendor extension table revision check from common file to the 3 CFI chip driver files, since the data structures and revisions handled by those data structures are specific to the chip driver. Modify the error message printed when the revision is unknown to be a KERN_ERR instead of WARNING since this will cause mtd to ignore the chip.
