[flashrom] MX25L128 Support

[Brian Rak]

So, I connected WP to ground (instead of leaving it unconnected), and 
reduced the speed (spispeed=8000).  Looking at a binary comparison of 
the original file versus what was actually written, it seems that it was 
writing parts of it successfully, but corrupting data every few bytes.

I'm guessing either the raspberry pi can't handle the higher speeds, or 
I'm getting interference from something.

Either way, I've done a couple erase, write, read cycles and it's been 
working fine.
