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