soc,vendorcode/amd/cezanne: add basic FSP integration

This is a trimmed-down version of the Cezanne FSP integration code, so
for example the UPD definitions are empty, which will be addressed
later. Since coreboot just leaves the UPD values at their default, this
is not a problem during the initial platform bring-up.
