Switch to AAI for some more SST chips

Browse Source 
Enable AAI for:
SST25VF016B
SST25VF040B{,.REMS}
SST25VF080B

Chips that support AAI via a different opcode are annotated with a comment:
SST25VF040.REMS
SST25LF040A.RES

SST25VF080B
Tested-by: Joshua Roys <roysjosh@gmail.com>
Write time (w/erase) went from 46 s to 21 s.

SST25VF016B
Tested-by: Noé Rubinstein <nrubinstein@avencall.com>
Write time (w/erase) on a dediprog went from 143 mins to 56 mins.

Corresponding to flashrom svn r1402.
