Add support for the AMIC A25L80P

This is a 1 MB SPI chip that seems to be straightforwardly related
to the AMIC A25L40PU, which has half the capacity but is otherwise
identical.

Datasheet is at http://www.amictechnology.com/pdf/A25L80P.pdf

flashrom -VE, -Vr, and -Vw has been tested using the AMD SB7x0
interface. Everything works fine... at least, I used it to upgrade my
BIOS and I've been able to reboot.

Corresponding to flashrom svn r1075.
