drivers/spi: Add support for adesto SPI flash parts
Adds support for the following Adesto Technologies SPI Flash parts. AT25DF081 AT25DF321 AT25DF641 It has been tested on an Orion VPX7654 board populated with an AT25DF321A part. The "08" and "64" densities have not been tested. These parts are the successors of the Atmel AT26DF line that was spun out or purchased by Adesto. In this patch, adesto.c is identical to winbond.c with part entries for the Adesto parts. The datasheet for the AT25DF parts includes a "100MHz" programming command in addition to the "85MHz" command that is currently used but this patch does not add support for that enhanced programming mode.
