Change in coreboot[master]: sb/intel/*: Use common SMBus functions

[Arthur Heymans (Code Review)]

Hello Patrick Rudolph, Paul Menzel, build bot (Jenkins),

I'd like you to reexamine a change.  Please visit

https://review.coreboot.org/19258

to look at the new patch set (#17).

Change subject: sb/intel/*: Use common SMBus functions
......................................................................

sb/intel/*: Use common SMBus functions

All Intel southbridges implement the same SMBus functions.
This patch replaces all these similar and mostly identical
implementations with a common file.

This also makes i2c block read available to all those southbridges.
If the northbridge has to read a lot of SPD bytes sequentially, using
this function can reduce the time being spent to read SPD five-fold.
