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.
