Use AAI for some SST chips
Patch updated, based on Joshua Roys' patch
http://patchwork.coreboot.org/patch/2065/
I double checked against the datasheets. Also wrapped the comments to
respect 80-columns line width.
Use AAI:
SST25VF016B
SST25VF040B{,.REMS}
SST25VF080B
Datasheets say AAI is supported, but via a different opcode:
SST25VF040.REMS
SST25LF040A.RES
