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.
