Convert SPI chips to partial write, but wrap the write functions in a compat layer to allow converting the rest of flashrom later
I actually have patches for most of the remaining conversion, but I wanted to get this out and reviewed first. Tested on Intel NM10 by David Hendricks. Corresponding to flashrom svn r1080.
