>From the datasheet (3368J–SEEPR) description:
     The AT25128A/256A provides 131,072/262,144 bits of serial
     electrically-erasable programmable read only memory (EEPROM)
     organized as 16,384/32,768 words of 8 bits each.

However QEMU models the flash size in bytes.
Correct the at25128a/at25256a entries to reflect the datasheet size.

This is not a regression, so can now wait for 2.13.
