Add detailed status register printing and unlocking for all ATMEL AT25* chips
Add support for Atmel AT25DF081A and AT25DQ161. Some chips require EWSR before WRSR, others require WREN before WRSR, and some support both variants. Add feature_bits to select the correct SPI command, and default to EWSR. Corresponding to flashrom svn r1115.
