Add support for SST SST25WF020A, SST25WF040B, SST25WF080B
Apart from the strange ID (using Sanyo's vendor ID 0x62) the main
difference from the plain SST25WF series is that they lack op codes
0xAD (AAI Word program) and 0x52 (32K erase). The smallest version
does not support dual I/O operations either.
SST25WF080B was tested under Linux with spidev.
Corresponding to flashrom svn r1901.
