[PATCH] mtd: chips: add SST38VF640x nor-flashes

Due to broken CFI, these flashes should be operated in jedec probe mode.
When you operate them in the CFI probe mode, you will get the wrong sector
size.And it will fail to set up the flash during the probe(CFI mode).
And i have tested it on my platform.
