sb/intel/common: Add early SPI code

All Intel southbridges with SPI perform this write. Put it inside a
function in common code. Use a different name to avoid a name clash.

As it is only one statement, make it inline so that it can be defined
on the header itself. It is only called once per southbridge anyway.
