Chips like the SST SST25VF080B can only handle single byte writes outside AAI mode
Change SPI architecture to handle 1-byte chunk chip writing differently
from 256-byte chunk chip writing.
Annotate SPI chip write functions with _256 or _1 suffix denoting the
number of bytes they write at maximum.
The 1-byte chunk writing is cut-n-pasted to different SPI drivers right
now. A later patch can move them to the generic spi_chip_write_1.
Corresponding to flashrom svn r485.
