[U-Boot] CFI flash broken for 8-bit bus

[Aaron Williams]

I'll post the patches as soon as I figure out how to get git to do it.

The patches are fairly clean and works well for both an 8-bit bus and a 16-bit 
bus.

My biggest obstical is that I'm not all that familiar with GIT and we use SVN 
internally.
