flashchips: Drop dead code of AT26DF321

The definition for the AT26DF321 has been commented out since it was
first added in 2008. The chip now appears to be obsolete, being marked
"obsolete" and unstocked at Digikey. It is also only referred to in
historical documents on the manufacturer's website (microchip.com).

To avoid further bitrot of this dead code, drop it.
