Felix Held 25aa5606c2 soc/amd/stoneyridge: factor out AGESA-wrapper related FCH functions
Split the code that gets called from the AGESA wrapper from the rest of
the FCH/southbridge code that directly interacts with the hardware.
Since the remaining parts of southbridge.c aren't used in romstage,
drop it from the list of build targets for romstage.
