spi: at25 driver is for EEPROM not FLASH
Add comment to at25 driver that it's for EEPROM chips, not FLASH chips ... the AT25 series has both types of chip, and sometimes they're even pin-compatible. The command sets are different, as is the treatment of erasure. (FLASH needs explicit erasure, but with EEPROM it's implicit.) Note that all vendors seem to have this same confusion in their *25* series SPI memory parts.
