fsp/gop: Add running the GOP to the choice of gfx init

The new config choice is called RUN_FSP_GOP. Some things had to happen
on the road:

  * Drop confusing config GOP_SUPPORT,
  * Add HAVE_FSP_GOP to chipsets that support it,
  * Make running the GOP an option for FSP2.0 by returning 0
    in random VBT getters.
