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.
