Program loading: Handoff cbmem_top via calling arguments
There are a lot of different implementations to pass information from romstage to ramstage. These could all be unified by passing this information via cbmem. Often however these methods exist for that very purpose. This solves this by passing cbmem_top via the programs arguments.
