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.
