Set w39v080fa to fully supported

I'm am flashing this chip several times a day. Also enable unlocking
which is only needed when running coreboot, that slipped in the original
commit and through the original review ;-) So it must be trivial enough.

Corresponding to flashrom svn r290 and coreboot v2 svn r3406.
