[coreboot] sb800 code derived from sb700 implementation

[She, Kerry]

Sorry to send again, forget the subject last email

I have made a little bit cleanup from the patches originally made by Bao Zheng,

This sb800 code is derived from sb700 implementation.

Release this patch is NOT to confusing people, but make other patches based on this implementation also works.

So this patch don’t need to be checked into the tree.
