soc/amd/*/romstage: factor out FSP-M call

Move the call into the FSP code to a file in the common AMD FSP code to
isolate the FSP-specific parts of the code and a preparation to make the
romstage of all non-CAR AMD SoCs common. Without isolating the call into
the FSP-M code, building the common romstage would fail for genoa_poc
due to fsp/api.h not being in the include path.
