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*)

This includes:
Bottom boot block:
* 16Mb/2MB:
QB25F160S33B8, QB25F016S33B8, QH25F160S33B8, QH25F016S33B8
* 32Mb/4MB:
QB25F320S33B8, QH25F320S33B8
* 64Mb/8MB:
QB25F640S33B8, QH25F640S33B8
Top boot block:
* 16Mb/2MB:
QB25F160S33T8, QB25F016S33T8, QH25F160S33T8, QH25F016S33T8
* 32Mb/4MB:

* 64Mb/8MB:
QB25F640S33T8, QH25F640S33T8
At least some seem to be marketed by other vendors (too?) but also with
Intel's vendor ID.
Besides a 0xC7 chip erase and a 0xD8 uniform 64kB block erase they
support also erasing the top/bottom 8 8kB blocks with opcode 0x40.
But since this command fails for all addresses outside those ranges,
it is not easily implemented with flashrom's current code base and
hence left out.

This does not only remove a huge pile of duplicate code, it does
also fix a bug in spi_disable_blockprotect_at25df(), which is also
a good example why duplicated code is a bad idea.

- Move all functions related to SPI status registers to a new file
spi25_statusreg.c. This includes the generic as well as the
SST-specific functions from spi25.c and the chip-specific functions
from a25.c and at25.c.
- introduce helper functions
* spi_prettyprint_status_register_hex()
* spi_prettyprint_status_register_bpl()
* spi_prettyprint_status_register_plain()
Use the latter on every compatible flash chip that has no better printlock
function set and get rid of the implicit pretty printing in the SPI probing
functions.
- remove
* spi_prettyprint_status_register_common()
* spi_prettyprint_status_register_amic_a25lq032() because it can be fully
substituted with spi_prettyprint_status_register_amic_a25l032().
* spi_prettyprint_status_register() (old switch, no longer needed)
- promote and export
* spi_prettyprint_status_register_amic_a25l05p() as spi_prettyprint_status_register_default_bp1().
* spi_prettyprint_status_register_amic_a25l40p() as spi_prettyprint_status_register_default_bp2().
* spi_prettyprint_status_register_st_m25p() as spi_prettyprint_status_register_default_bp3().
- add #define TEST_BAD_REW and use it for a number of Atmel chips which
had only TEST_BAD_READ set even though they dont have erasers or a write
function set.
