soc/amd/common: Introduce module_dispatch()

This change removes all the separate entrypoint dispatch
functions as they all share the same pattern.

Furthermore, none of the function definitions under vendorcode
binaryPI/AGESA.c file have proper declarations, the ones compiler
picks up from AGESA.h are for the internal implementations and
with sanely organized headerfiles would not be exposed outside
the build of AGESA at all.
