Message:

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.
