Add support for Sanyo LE25FU406B

It is very similar to LE25FW418A, except for HD_READ support (that
is not implemented in flashrom anyway yet) and allowed voltage range.

Probing, erasing, reading and writing has been tested.

This chip is found on Seagate Constellation hard drives.

Corresponding to flashrom svn r1791.
