Add support for Atmel's AT25F series of SPI flash chips

Browse Source 
This adds support for the following chips:
 - AT25F512, AT25F512A, AT25F512B
 - AT25F1024, AT25F1024A
 - AT25F2048
 - AT25F4096

Besides the definitions of the the chips in flashchips.c this includes
- a dedicated probing method (probe_spi_at25f)
- pretty printing methods (spi_prettyprint_status_register_at25f*), and
- unlocking methods (spi_disable_blockprotect_at25f*)

Corresponding to flashrom svn r1637.
