Implement read support for the following Atmel chips

AT25DF021
AT25DF041A
AT25DF081
AT25DF161
AT25DF321A
AT25DF641
AT25F512B
AT25FS010
AT25FS040
AT26DF041
AT26DF081A
AT26DF161
AT26DF161A
AT26DF321
AT26F004

I double-checked the data sheets and am confident this will work.

Corresponding to flashrom svn r344 and coreboot v2 svn r3756.
