console: Drop driver list in ramstage
This framework was only available in ramstage. So we had to define console output functions separately for bootblock, romstage and SMM. Follow-up patches will re-enable all the consoles removed here, in a more flexible fashion, and with less lines-of-code and copy-paste. Also the driver list is not in a well-defined order and some of the loops could exit without visiting all drivers. NOTE: This build has no console in ramstage.
