Add support for Adesto AT25SF128A

Browse Source 
The following adds support for the Adesto AT25SF128A-SHB-T part.
We have varied the correct chip name is reported as well as write
and read 16MBytes of random data and verified the checksum's match.
Further, --wp-list appears to report the correct ranges.

BUG=None
BRANCH=none
TEST=Ran flashrom with a Dediprog SF100, RW random data and checksum
matched.

(cherry picked from commit 1fa87e058b72a2de1e9127a45e9978361de48479)

Note: this does not include the changes made to writeprotect.c in the
original patch, as they depend on a large amount of additional
writeprotect code that is currently only present in the cros tree, and
the intention here is just to reduce the diff in flashchips.c.
The `.wp` field has also been removed.
